Eugene Koifman created HIVE-7249:
------------------------------------
Summary: HiveTxnManager.closeTxnManger() throws if called after
commitTxn()
Key: HIVE-7249
URL: https://issues.apache.org/jira/browse/HIVE-7249
Project: Hive
Issue Type: Bug
Components: Locking
Affects Versions: 0.13.1
Reporter: Eugene Koifman
Assignee: Alan Gates
I openTxn() and acquireLocks() for a query that looks like "INSERT INTO T
PARTITION(p) SELECT * FROM T".
Then I call commitTxn(). Then I call closeTxnManger() I get an exception
saying lock not found (the only lock in this txn). So it seems TxnMgr doesn't
know that commit released the locks.
Here is the stack trace and some log output which maybe useful:
