      Description

      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:
