[jira] [Created] (HIVE-11388) there should only be 1 Initiator for compactions per Hive installation

Eugene Koifman created HIVE-11388:
-------------------------------------

             Summary: there should only be 1 Initiator for compactions per Hive installation
                 Key: HIVE-11388
                 URL: https://issues.apache.org/jira/browse/HIVE-11388
             Project: Hive
          Issue Type: Bug
          Components: Transactions
    Affects Versions: 1.0.0
            Reporter: Eugene Koifman
            Assignee: Eugene Koifman


org.apache.hadoop.hive.ql.txn.compactor.Initiator is a thread that runs inside the metastore service to manage compactions of ACID tables.  There should be exactly 1 instance of this thread (even with multiple Thrift services).

This is documented in https://cwiki.apache.org/confluence/display/Hive/Hive+Transactions#HiveTransactions-Configuration but not enforced.

Should add enforcement, since more than 1 Initiator could cause concurrent attempts to compact the same table/partition - which will not work.
