-------------------------------------
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.
