We use MOR Hudi table , We read kinesis stream and process in AWS EMR using spark streaming.
We use inline compaction and cleanup based on the commits,
Though compaction and cleanup is running we see some of hudi log files that are generated while ingestion are not getting cleared fully.
We process with batch interval of 5 mints for every 5 mints we do one hudi commit.
Below are our hudi configs
DataSourceWriteOptions.TABLE_TYPE.key() -> DataSourceWriteOptions.MOR_TABLE_TYPE_OPT_VAL,
DataSourceWriteOptions.RECORDKEY_FIELD.key() -> "guid",
DataSourceWriteOptions.PARTITIONPATH_FIELD.key() -> "collectionName",
DataSourceWriteOptions.PRECOMBINE_FIELD.key() -> "operationTime",
DataSourceWriteOptions.HIVE_PARTITION_FIELDS.key() -> "collectionName",
DataSourceWriteOptions.HIVE_PARTITION_EXTRACTOR_CLASS.key() -> classOf[MultiPartKeysValueExtractor].getName,
DataSourceWriteOptions.HIVE_SYNC_MODE.key() -> "hms",
DataSourceWriteOptions.HIVE_USE_JDBC.key() -> "false",*/
HoodieCompactionConfig.INLINE_COMPACT_TRIGGER_STRATEGY.key() -> CompactionTriggerStrategy.TIME_ELAPSED.name,
HoodieCompactionConfig.INLINE_COMPACT_TIME_DELTA_SECONDS.key() -> String.valueOf(60 * 6 * 60),
HoodieCompactionConfig.CLEANER_POLICY.key() -> HoodieCleaningPolicy.KEEP_LATEST_COMMITS.name(),
HoodieCompactionConfig.CLEANER_COMMITS_RETAINED.key() -> "228",

Research direction
Start by reviewing the MOR compaction and cleaner settings in the issue, especially the retained-commit values, then inspect the attached snapshots and reproduce the behavior with Hudi 0.9, Spark 3.2.1, EMR 6.7, and S3. Done means determining why generated log files remain after compaction and cleanup, with the relevant configuration or reproduction narrowed down.
