> CompactorMR submits MR job to do compaction and waits for completion.
> If the metastore need to be restarted, it will kill in-flight compactions.
> I ideally we'd want to add job ID to the COMPACTION_QUEUE table (and include that in SHOW COMPACTIONS) and poll for it or register a callback so that the job survives Metastore restart
