Peter Varga created HIVE-23725: ---------------------------------- Summary: ValidTxnManager snapshot outdating causing partial reads in merge inserst Key: HIVE-23725 URL: https://issues.apache.org/jira/browse/HIVE-23725 Project: Hive Issue Type: Bug Reporter: Peter Varga Assignee: Peter Varga
When the ValidTxnManager invalidates the snapshot during merge insert and starts to read committed transactions that were not committed when the query compilation happened, it can cause partial read problems if the committed transaction created new partition in the source or target table. The solution should be not only fix the snapshot but also recompile the query and acquire the locks again -- This message was sent by Atlassian Jira (v8.3.4#803005)
