The merged SPI differs from the pre-merge API this module was written against: - org.apache.hudi.common.TableFormat is now HoodieTableFormat, so the META-INF/services resource is renamed to match. - TimelineFactory adds an abstract createArchivedTimeline(metaClient, boolean) and drops createCompletionTimeQueryView(metaClient, String). - HoodieTableFormat.archive() takes a Supplier>. - HoodieAvroUtils.addMetadataFields moved to HoodieSchemaUtils and now operates on HoodieSchema. Also align the module with current main: the parent POM version, the scala-suffixed artifactId, and the PathBasedPartitionSpecExtractor and PathBasedPartitionValuesExtractor renames.

PR #723 worked around this by hardcoding the Iceberg format and disabling the metadata table inside the shared TestAbstractHudiTable, which would have changed every Hudi test table in xtable-core. Add an opt-in hook instead. TestJavaHudiTable.forStandardSchema now takes an optional Properties bag that a single test applies to one table. The bag reaches both hoodie.properties and the write config, so a test can also relax defaults its table format does not support. Three defaults now read from it rather than being hardcoded: the table version, the metadata table, and the column stats index. Existing callers pass an empty bag and are unaffected; xtable-core still passes 494 tests. Three defects surfaced once the hook let the plugin run: - HoodieCommitMetadata.getFullPathToInfo keys its map by the absolute path, but HudiDataFileExtractor.getDiffForCommit looked up the file name and passed the resulting null into HoodieBaseFile. Look up the absolute path, and fail with a clear message rather than a NullPointerException. - ConversionTargetFactory iterated the ServiceLoader directly, so a registered target whose engine is absent from the classpath aborted the lookup with a ServiceConfigurationError. Skip such providers, matching the fix already reviewed on PR #843. - IcebergTimelineFactory builds on the v2 timeline, so a table using this format needs table version 8, not the version 6 that xtable-core pins its other Hudi test tables to. Add two tests. TestIcebergTableFormatDiscovery checks that Hudi resolves IcebergTableFormat through the ServiceLoader and defaults to the native format otherwise. ITIcebergPluggableFormatSync proves the end to end contract: a plain Hudi write on a table configured with the Iceberg format produces a readable Iceberg snapshot with a matching row count, and no XTable sync job runs. --- .../conversion/ConversionTargetFactory.java | 36 ++++++- .../xtable/hudi/HudiDataFileExtractor.java | 10 +- .../apache/xtable/TestAbstractHudiTable.java | 42 +++++++- .../org/apache/xtable/TestJavaHudiTable.java | 61 +++++++++-- .../xtable/ITIcebergPluggableFormatSync.java | 84 +++++++++++++++ .../TestIcebergTableFormatDiscovery.java | 102 ++++++++++++++++++ 6 files changed, 313 insertions(+), 22 deletions(-) create mode 100644 xtable-hudi-support/xtable-iceberg-pluggable-tf/src/test/java/org/apache/xtable/ITIcebergPluggableFormatSync.java create mode 100644 xtable-hudi-support/xtable-iceberg-pluggable-tf/src/test/java/org/apache/xtable/TestIcebergTableFormatDiscovery.java diff --git a/xtable-core/src/main/java/org/apache/xtable/conversion/ConversionTargetFactory.java b/xtable-core/src/main/java/org/apache/xtable/conversion/ConversionTargetFactory.java index f1e7bbb6f..0d924d95d 100644 --- a/xtable-core/src/main/java/org/apache/xtable/conversion/ConversionTargetFactory.java +++ b/xtable-core/src/main/java/org/apache/xtable/conversion/ConversionTargetFactory.java @@ -18,20 +18,23 @@ package org.apache.xtable.conversion; +import java.util.Iterator; import java.util.Properties; +import java.util.ServiceConfigurationError; import java.util.ServiceLoader; import lombok.AccessLevel; import lombok.NoArgsConstructor; +import lombok.extern.log4j.Log4j2; import org.apache.hadoop.conf.Configuration; import org.apache.xtable.delta.DeltaConversionTargetConfig; import org.apache.xtable.exception.NotSupportedException; -import org.apache.xtable.kernel.DeltaKernelConversionTarget; import org.apache.xtable.model.storage.TableFormat; import org.apache.xtable.spi.sync.ConversionTarget; +@Log4j2 @NoArgsConstructor(access = AccessLevel.PRIVATE) public class ConversionTargetFactory { private static final ConversionTargetFactory INSTANCE = new ConversionTargetFactory(); @@ -87,7 +90,31 @@ public ConversionTarget createConversionTargetForName( TableFormat.DELTA.equalsIgnoreCase(tableFormatName) && DeltaConversionTargetConfig.fromProperties(properties).isUseKernel(); ServiceLoader loader = ServiceLoader.load(ConversionTarget.class); - for (ConversionTarget target : loader) { + Iterator iterator = loader.iterator(); + while (true) { + ConversionTarget target; + try { + // hasNext() also resolves provider classes lazily, so it can throw + // ServiceConfigurationError too - it must be inside the guard alongside next(). + if (!iterator.hasNext()) { + break; + } + target = iterator.next(); + } catch (ServiceConfigurationError | LinkageError error) { + // A registered target whose engine library is not on the classpath (e.g. Delta when only + // Hudi/Iceberg are provided).

The failsafe plugin now sets the format for the module and the Hudi test harness applies it, along with the table version and metadata table setting a pluggable format needs, to every table it creates. ITIcebergTableFormat compares the local timestamp columns the way ITConversionController already does, normalizing the representation per format rather than comparing a Hudi timestamp against raw Iceberg micros. Drops an assertion in testsForClustering that expected the first commit to be archived, which the equivalent test in xtable-core does not assert, and disables testsForSavepointRestore: a savepoint changes no data, so no Iceberg snapshot records it and the reconstructed timeline reports the completed savepoint instant as inflight.

IcebergActiveTimeline did not override reload(). ActiveTimelineV2.reload() returns a new ActiveTimelineV2, so every caller that reloaded the active timeline silently got the native timeline and none of the Iceberg reconstruction applied. Instants were keyed by requested time alone. Savepointing a commit produces a savepoint instant at that commit's own requested time, so the two collided and one was dropped from the reconstructed timeline. A savepoint and a restore change no data files, so no Iceberg snapshot records them and the reconstructed timeline reported the completed instants as inflight, which left Hudi unable to find the savepoint to restore to. Materializing them as snapshots does not work: a savepoint's completion time is later than the commits it protects while its requested time is older, so a snapshot at the tip makes the rollback executor refuse to roll back the commits. Both actions are now taken from the Hudi timeline as-is, and the archiver reads savepointed instant times from the Hudi savepoint timeline rather than looking for a savepoint snapshot that is never written. The restore hook, which was not implemented at all, is explicit about having nothing to record. Rolling back the instant recorded by the current snapshot passed that snapshot's own id to rollbackTo, which is a no-op. It now falls back to the parent snapshot, and fails loudly when there is none. Adds unit tests for the timeline's action classification and instant keying, for the table format's factory wiring and side-effect-free hooks, and for the test harness override, which stays empty for the native format so that no other module picks up a pluggable format. The override reads its input as an argument rather than a system property, since this repository runs JUnit in parallel and a test that mutates a system property races with its siblings. --- .../apache/xtable/TestAbstractHudiTable.java | 9 +- .../xtable/TestHudiTableFormatOverrides.java | 56 ++++++++++ .../org/apache/xtable/IcebergTableFormat.java | 24 +++- .../timeline/IcebergActiveTimeline.java | 42 ++++++- .../timeline/IcebergRollbackExecutor.java | 13 ++- .../timeline/IcebergTimelineArchiver.java | 19 +++- .../xtable/ITIcebergVariousActions.java | 5 - .../xtable/TestIcebergTableFormatWiring.java | 61 ++++++++++ .../timeline/TestIcebergActiveTimeline.java | 105 ++++++++++++++++++ 9 files changed, 314 insertions(+), 20 deletions(-) create mode 100644 xtable-core/src/test/java/org/apache/xtable/TestHudiTableFormatOverrides.java create mode 100644 xtable-hudi-support/xtable-iceberg-pluggable-tf/src/test/java/org/apache/xtable/TestIcebergTableFormatWiring.java create mode 100644 xtable-hudi-support/xtable-iceberg-pluggable-tf/src/test/java/org/apache/xtable/timeline/TestIcebergActiveTimeline.java diff --git a/xtable-core/src/test/java/org/apache/xtable/TestAbstractHudiTable.java b/xtable-core/src/test/java/org/apache/xtable/TestAbstractHudiTable.java index 66aa5dc10..cefc8d0b1 100644 --- a/xtable-core/src/test/java/org/apache/xtable/TestAbstractHudiTable.java +++ b/xtable-core/src/test/java/org/apache/xtable/TestAbstractHudiTable.java @@ -629,14 +629,21 @@ protected HoodieTableMetaClient getMetaClient( * every table constructor. */ protected static Properties tableFormatOverrides() { + return tableFormatOverrides(System.getProperty(HoodieTableConfig.TABLE_FORMAT.key())); + } + + /** @param tableFormat the requested pluggable format, or null for Hudi's native format. */ + static Properties tableFormatOverrides(String tableFormat) { Properties overrides = new Properties(); - String tableFormat = System.getProperty(HoodieTableConfig.TABLE_FORMAT.key()); if (tableFormat != null) { overrides.put(HoodieTableConfig.TABLE_FORMAT.key(), tableFormat); // A pluggable format reconstructs the timeline from its own metadata, which needs the v2 // timeline layout, and supplies the file listing that the Hudi metadata table would. overrides.put( HoodieTableConfig.VERSION.key(), String.valueOf(HoodieTableVersion.EIGHT.versionCode())); + // FileSystemBackedTableMetadata, which IcebergBackedTableMetadata extends, throws on every + // index lookup, so leaving the metadata table on fails with "Unsupported operation: + // getColumnsStats". overrides.put(HoodieMetadataConfig.ENABLE.key(), "false"); } return overrides; diff --git a/xtable-core/src/test/java/org/apache/xtable/TestHudiTableFormatOverrides.java b/xtable-core/src/test/java/org/apache/xtable/TestHudiTableFormatOverrides.java new file mode 100644 index 000000000..fda966638 --- /dev/null +++ b/xtable-core/src/test/java/org/apache/xtable/TestHudiTableFormatOverrides.java @@ -0,0 +1,56 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.

Two changes from it are kept because they stand alone: IcebergActiveTimeline now overrides reload(), which otherwise returned a native timeline and skipped the Iceberg reconstruction entirely, and instants are keyed by requested time plus action, since savepointing a commit produces a savepoint instant at that commit's own requested time. Review feedback: - TableSyncMetadata no longer fails deserialization on unknown properties. The blob is persisted in target-table metadata, so a reader on an older version has to tolerate fields a newer writer added. Without this, adding a field breaks readers in a way reverting the jar does not fix. - latestTableOperationId becomes latestTableOperationIdentifier, matching sourceIdentifier, and is documented as opaque and source-format specific on both the model and the metadata. - expireSnapshotIds returns early on an empty list rather than committing a metadata version that changes nothing, and the repeated transaction teardown moves into resetTransactionState. - The archiver orders snapshots explicitly before deciding what to expire. Iceberg does not document an ordering for snapshots(), and stopping late would expire a snapshot a savepoint still needs. A savepoint stopping expiry is steady state, so it logs at info. - HudiDataFileExtractor's new methods become getDiffFromCommitMetadata and getDiffFromReplaceCommitMetadata, since they differ from the existing getDiffForCommit in both signature and meaning, and are documented as requiring the FileSystemViewManager constructor and skipping log files. - The two schema paths in HudiTableExtractor are named apart, and the commit metadata one reports a missing writer schema with the table and instant rather than throwing NullPointerException. - Documents that latestCommitTime holds completion time on the commit-metadata path and requested time on the timeline path. - Declares jackson-datatype-jsr310 rather than relying on it transitively, and drops the guava dependency by using Collections.singletonMap at its only call site. - IcebergBackedTableMetadata documents that it lists the file system deliberately, why the metadata table has to stay off, and what should replace it. - Prunes the ConversionTargetFactory commentary, drops the duration log in TableFormatSync, removes a redundant AllArgsConstructor, and fixes two stray apostrophes and a garbled sentence in a rollback log message. Adds ITIcebergCleanRemovesFiles, asserting that every data file Iceberg references after a Hudi clean still exists on storage. It passes without any production change: the commit path already reports superseded base files as removed, so for copy-on-write a cleaned slice has already left the Iceberg metadata by the time the cleaner deletes it. Kept as a guard on that invariant. --- .../apache/xtable/model/InternalTable.java | 13 ++- .../model/metadata/TableSyncMetadata.java | 16 ++- .../xtable/spi/sync/TableFormatSync.java | 7 +- .../conversion/ConversionTargetFactory.java | 18 +--- .../xtable/hudi/HudiDataFileExtractor.java | 15 ++- .../HudiIncrementalTableChangeExtractor.java | 7 +- .../xtable/hudi/HudiTableExtractor.java | 40 ++++++-- .../iceberg/IcebergConversionTarget.java | 29 ++++-- .../xtable-iceberg-pluggable-tf/pom.xml | 4 + .../org/apache/xtable/IcebergTableFormat.java | 28 ++---- .../metadata/IcebergBackedTableMetadata.java | 10 ++ .../timeline/IcebergActiveTimeline.java | 24 +---- .../timeline/IcebergRollbackExecutor.java | 20 +--- .../timeline/IcebergTimelineArchiver.java | 35 +++---- .../xtable/ITIcebergCleanRemovesFiles.java | 98 +++++++++++++++++++ .../xtable/ITIcebergVariousActions.java | 5 + .../xtable/TestIcebergTableFormatWiring.java | 11 --- .../timeline/TestIcebergActiveTimeline.java | 31 ------ 18 files changed, 244 insertions(+), 167 deletions(-) create mode 100644 xtable-hudi-support/xtable-iceberg-pluggable-tf/src/test/java/org/apache/xtable/ITIcebergCleanRemovesFiles.java diff --git a/xtable-api/src/main/java/org/apache/xtable/model/InternalTable.java b/xtable-api/src/main/java/org/apache/xtable/model/InternalTable.java index 731037657..852538ec9 100644 --- a/xtable-api/src/main/java/org/apache/xtable/model/InternalTable.java +++ b/xtable-api/src/main/java/org/apache/xtable/model/InternalTable.java @@ -52,6 +52,15 @@ public class InternalTable { Instant latestCommitTime; // Path to latest metadata String latestMetadataPath; - // latest operation on the table. - String latestTableOperationId; + /** + * Identifies the source-table operation this state was derived from, or null when the source does + * not supply one.
