-----------------------------------
Summary: Compaction Initiator ignores datas inserted by Stream
Data Ingest
Key: HIVE-20852
URL: https://issues.apache.org/jira/browse/HIVE-20852
Project: Hive
Issue Type: Bug
Components: API
Affects Versions: 3.1.0
Reporter: Kei Miyauchi
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.
