> Dropping a table can cause NPEs in the compactor
> ------------------------------------------------
>
> Key: HIVE-10595
> URL: https://issues.apache.org/jira/browse/HIVE-10595
> Project: Hive
> Issue Type: Bug
> Components: Metastore
> Affects Versions: 0.14.0, 1.0.0, 1.1.0
> Reporter: Alan Gates
> Assignee: Alan Gates
> Attachments: HIVE-10595.patch
>
>
> Reproduction:
> # start metastore with compactor off
> # insert enough entries in a table to trigger a compaction
> # drop the table
> # stop metastore
> # restart metastore with compactor on
> Result: NPE in the compactor threads. I suspect this would also happen if
> the inserts and drops were done in between a run of the compactor, but I
> haven't proven it.
