> Key: HIVE-20852
> URL: https://issues.apache.org/jira/browse/HIVE-20852
> Project: Hive
> Issue Type: Bug
> Components: API, Transactions
> Affects Versions: 3.1.0
> Reporter: Kei Miyauchi
> Priority: Major
>
> HI,
> Before compaction, Initiator decides whether a table/partition is potentialCompaction by querying COMPLETE_TXN_COMPONENT.
> But I found the transactions which committed by Stream Data Ingest is not stored on COMPLETE_TXN_COMPONENT. This is because the statement "insert into COMPLETED_TXN_COMPONENTS (ctc_txnid, ctc_database, ctc_table, ctc_partition, ctc_writeid, ctc_update_delete) select tc_txnid, tc_database, tc_table, tc_partition, tc_writeid, 'N' from TXN_COMPONENTS where tc_txnid = (id)" fails.
> I found INSERT statement to TXN_COMPONENTS isn't fired. select subquery above returns 0 row.
