Alan Gates updated HIVE-8258:
-----------------------------
Attachment: HIVE-8258.4.patch
A new version of the patch that actually makes sure the cleaner goes through
the loop rather than relying on timing and hoping it works out.
> Compactor cleaners can be starved on a busy table or partition.

> Currently the cleaning thread in the compactor does not run on a table or
> partition while any locks are held on this partition. This leaves it open to
> starvation in the case of a busy table or partition. It only needs to wait
> until all locks on the table/partition at the time of the compaction have
> expired. Any jobs initiated after that (and thus any locks obtained) will be
> for the new versions of the files.
