Eugene Koifman commented on HIVE-18693:
---------------------------------------
this won't enqueue any compaction requests so CompactorMR will never run, i.e.
it won't clean aborted dirs
also, it will not clean relevant entries from txn_components or
completed_txn_componentes.
The test should look at the directories on the file system and make sure that
they are actually deleted.
> Snapshot Isolation does not work for Micromanaged table when a insert
> transaction is aborted
