> Key: HIVE-26858
> URL: https://issues.apache.org/jira/browse/HIVE-26858

> Issue Type: Bug
> Components: Hive
> Reporter: KIRTI RUGE
> Assignee: KIRTI RUGE
> Priority: Major
>
> If for some reason housekeeper service wasn't running, when activated it
> could cause OOM. showCompactions & purgeCompactionHistory loads the complete
> history of events into the heap that should be reviewed.
> purgeCompactionHistory might be refactored with batching or replaced with a
> complex delete query instead of `select` first and then `delete`.
