---------------------------------
Summary: Handle race condition between compaction txn abort/commit
and heartbeater
Key: HIVE-25740
URL: https://issues.apache.org/jira/browse/HIVE-25740
Project: Hive
Issue Type: Bug
Reporter: Marton Bod
Assignee: Marton Bod
This issue is the following: once the compaction worker finishes,
commitTxn/abortTxn is invoked first, and the heartbeater thread is only
interrupted after that. This can lead to race conditions where the txn has
already been deleted from the backend DB via commit/abort, but the concurrently
running heartbeater thread still attempts to send a last heartbeat after that,
but the txn id won't be found in the DB, leading to {{{}NoSuchTxnException{}}}.
