[jira] [Created] (HIVE-11916) TxnHandler.getOpenTxnsInfo() and getOpenTxns() may produce inconsistent result

Eugene Koifman created HIVE-11916:
-------------------------------------

             Summary: TxnHandler.getOpenTxnsInfo() and getOpenTxns() may produce inconsistent result
                 Key: HIVE-11916
                 URL: https://issues.apache.org/jira/browse/HIVE-11916
             Project: Hive
          Issue Type: Bug
          Components: Transactions
    Affects Versions: 1.0.1
            Reporter: Eugene Koifman
            Assignee: Eugene Koifman


both run at READ_COMMITTED isolation level and each runs 2 queries.
Thus it's possible for a new txn to start/commit after hight water mark is recored by these methods.  So the returned list may have txns above the HWM.

This can be fixed by adding "WHERE TXN_ID < hwm" clause to 2nd query in each case
