[jira] [Updated] (HIVE-11388) Allow ACID Compactor components to
run in multiple metastores
[ https://issues.apache.org/jira/browse/HIVE-11388?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Eugene Koifman updated HIVE-11388:
----------------------------------
Description:
(this description is no loner accurate; see further comments)
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.
