Review comment:
During a log analysis with @pvary we realized that there's no info level
log entry at the beginning of the worker process, which makes a bit more
difficult to track down compactions which failed on the checks and did not
reach the
` LOG.info("Starting " + ci.type.toString() + " compaction for " +
ci.getFullPartitionName() + ", id:" +
ci.id + " in " + compactionTxn + " with compute stats set to
" + computeStats);
`
line. So we agreed to change this to info level.

> The
> org.apache.hadoop.hive.ql.txn.compactor.Worker#findNextCompactionAndExecute
> method does several checks (The table/partition exists, is not sorted, there
> are enough files to compact, etc.) before it actually executes the compaction
> request. If the compaction request fails on any of these checks, it is put to
> "SUCCEEDED" state which is often misleading for users. SHOW COMPACTIONS will
> show these requests as succeeded without an error, while the table is not
> compacted at all.
> For these cases, the state should be "REFUSED" instead of "SUCCEEDED" among
> with the appropriate error message.
