Description

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

Also,

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

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

        LOG.info(quoteString(key) + " locked by " + quoteString(TxnHandler.hostname));

and a corresponding "unlock" msg which flood the metastore log.
