>             Project: Hive
>          Issue Type: Bug
>          Components: Metastore
>    Affects Versions: 0.14.0, 1.0.0, 1.1.0

> 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.
