-------------------------------------
Summary: Compaction for MM runs Cleaner - needs test once IOW is
supported
Key: HIVE-17660
URL: https://issues.apache.org/jira/browse/HIVE-17660
Project: Hive
Issue Type: Sub-task
Components: Transactions
Reporter: Eugene Koifman
Deletion of aborted deltas happens from CompactorMR.run() i.e. from Worker
but the Worker still sets compaction_queue entry to READY_FOR_CLEANING.
This is not needed if there are no base_N dirs which can be created by Insert
Overwrite
In this case we can't delete deltas < N until we know no one is reading them,
i.e. in Cleaner
