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. was: org.apache.hadoop.hive.ql.txn.compactor.Initiator is a thread that runs inside the metastore service to manage compactions of ACID tables.
