Review comment:
Since the compaction will be rescheduled when the table changes, REFUSED
can be thought of 'The current state of the table is refused.' The main
difference is whether we want to keep the original request and process it once
possible, or just refuse it and process request only which fulfill all criteria
at the time of checking.

> 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.
