Date Tue, 29 Nov 2016 21:56:58 GMT
Eugene Koifman created HIVE-15309:
-------------------------------------

             Summary: Miscellaneous logging clean up
                 Key: HIVE-15309
                 URL: https://issues.apache.org/jira/browse/HIVE-15309
             Project: Hive
          Issue Type: Bug
          Components: Transactions
            Reporter: Eugene Koifman
            Assignee: Eugene Koifman


OrcAcidUtils.getLastFlushLength() should check for file existence first.  Currently causes
unnecessary/confusing logging:

org.apache.hadoop.ipc.RemoteException(java.io.FileNotFoundException): File does not exist:

{noformat}

Also,
{noformat}
2016-08-02 01:05:01,107 INFO  [org.apache.hadoop.hive.ql.txn.AcidHouseKeeperService-0]: txn.TxnHandler
(TxnHandler.java:timeOutLocks(2836)) - Deleted 9 ext locks from HIVE_LOCKS due to timeout
(vs. 1 found. List: [738]) maxHeartbeatTime=1470099601000
{noformat}

Note that the msg says "Deleted 9 ext locks..."  It actually delete 1 ext which has 9 internal
components.  Need to follow up on this.

Also,
TxnHandler has
{noformat}
        LOG.info(quoteString(key) + " locked by " + quoteString(TxnHandler.hostname));
{noformat}
and a corresponding "unlock" msg which flood the metastore log.
