Alan Gates updated HIVE-10595:
------------------------------
Attachment: HIVE-10595.patch
The attached patch makes the following changes:
# The info message for initiator when it discovers a missing table now says
that the table may have been a temp or may have been dropped.
# Worker and cleaner threads now properly check for the table to be compacting
being null, and give an info message saying they assume the table has been
dropped.
# All three threads now properly handle the case where the partition is dropped
and give an info message rather than attempt to compact the table.
> 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.
