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. TableSyncMetadata keeps a four-argument of() overload so existing callers do not change. Add delta-core to the module test scope, because the shared HudiTestUtil.getSparkConf registers the Delta catalog and extension. --- .../model/metadata/TableSyncMetadata.java | 6 +++++- .../xtable/hudi/HudiDataFileExtractor.java | 2 +- .../apache/xtable/hudi/HudiTableExtractor.java | 8 +++++--- .../xtable-iceberg-pluggable-tf/pom.xml | 10 ++++++++-- .../org/apache/xtable/IcebergTableFormat.java | 17 +++++++++-------- .../xtable/timeline/IcebergTimelineFactory.java | 12 ++++++------ ...=> org.apache.hudi.common.HoodieTableFormat} | 0 .../apache/xtable/ITIcebergVariousActions.java | 15 ++++++++------- .../TestIcebergBackedTableMetadata.java | 2 -- .../timeline/TestIcebergActiveTimeline.java | 2 -- 10 files changed, 42 insertions(+), 32 deletions(-) rename xtable-hudi-support/xtable-iceberg-pluggable-tf/src/main/resources/META-INF/services/{org.apache.hudi.common.TableFormat => org.apache.hudi.common.HoodieTableFormat} (100%) diff --git a/xtable-api/src/main/java/org/apache/xtable/model/metadata/TableSyncMetadata.java b/xtable-api/src/main/java/org/apache/xtable/model/metadata/TableSyncMetadata.java index 1da9f3d9c..c2f6bde20 100644 --- a/xtable-api/src/main/java/org/apache/xtable/model/metadata/TableSyncMetadata.java +++ b/xtable-api/src/main/java/org/apache/xtable/model/metadata/TableSyncMetadata.java @@ -74,7 +74,11 @@ public static TableSyncMetadata of( String sourceTableFormat, String sourceIdentifier) { return TableSyncMetadata.of( - lastInstantSynced, instantsToConsiderForNextSync, sourceTableFormat, sourceIdentifier, null);

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).
