> Compaction should handle a case when it produces no output

> Key: HIVE-18429
> URL: https://issues.apache.org/jira/browse/HIVE-18429
> Project: Hive
> Issue Type: Bug
> Components: Transactions
> Affects Versions: 1.0.0
> Reporter: Eugene Koifman
> Assignee: Eugene Koifman
> Attachments: HIVE-18429.01.patch, HIVE-18429.02.patch
>
>
> Suppose we start with empty delta_8_8 and delta_9_9 and compaction runs.
> It will currently produce an MR job with 0 splits and so
> {{CompactorMR.TMP_LOCATION}} never gets created. This causes
> {{CompactorOutputCommitted.commitJob()}} to fail when it tries to do
> {{FileStatus[] contents = fs.listStatus(tmpLocation);}} since tmpLocation
> doesn't exist.
> If compactor fails to produce delta_8_9 here it will fail to do further
> compaction unless new delta with data is created.
> If the number of empty deltas is > than
> HiveConf.ConfVars.COMPACTOR_MAX_NUM_DELTA, compaction will not be able to
> proceed at all.
> It should produce a delta_8_9 in this case even if it's empty.
> The error (in the log of standalone metastore process) would look like this
