Karen Coppage created HIVE-22593: ------------------------------------ Summary: Dynamically partitioned MM (insert-only ACID) table isn't compacting automatically Key: HIVE-22593 URL: https://issues.apache.org/jira/browse/HIVE-22593 Project: Hive Issue Type: Bug Reporter: Karen Coppage Assignee: Karen Coppage
Dynamic partitions of MM tables aren't entered into the HMS table TXN_COMPONENTS. On inserting into such tables we see this line in the HMS log: {code:java} Expected to move at least one record from txn_components to completed_txn_components when committing txn!{code} (This is not the case for non-partitioned MM tables.) Since the partitions aren't entered into COMPLETED_TXN_COMPONENTS, they aren't considered for automatic compaction. Probably the culprit is org.apache.hadoop.hive.ql.metadata.Hive#loadDynamicPartitions which has an isAcid parameter that is always false regarding MM tables, and also because MM tables' "write type" is AcidUtils.Operation.NOT_ACID and not INSERT. -- This message was sent by Atlassian Jira (v8.3.4#803005)
