-------------------------------------
Summary: Restarting Metastore kills Compactions
Key: HIVE-11685
URL: https://issues.apache.org/jira/browse/HIVE-11685
Project: Hive
Issue Type: Improvement
Components: Metastore, Transactions
Affects Versions: 1.0.1
Reporter: Eugene Koifman
Assignee: Eugene Koifman
CompactorMR submits MR job to do compaction and waits for completion.
If the metastore need to be restarted, it will kill in-flight compactions.
I ideally we'd want to add job ID to the COMPACTION_QUEUE table (and include
that in SHOW COMPACTIONS) and poll for it or register a callback so that the
job survives Metastore restart
