> Key: HIVE-25442
> URL: https://issues.apache.org/jira/browse/HIVE-25442
> Project: Hive
> Issue Type: Improvement
> Reporter: Zoltan Chovan
> Assignee: Zoltan Chovan
> Priority: Major
>
> In checkFailedCompactions (which is called for every partition in the list of potentials to compact) we select from metadata table COMPLETED_COMPACTIONS.
> But the Initiator main loop already has a ShowCompactResponse. We can use that instead.
> For cases where metadata is huge, this will help speed up the Initiator.
