-------------------------------------

             Summary: LP Bug: 1442483 - SQL queries hang when Region Server goes down
                 Key: TRAFODION-1151
                 URL: https://issues.apache.org/jira/browse/TRAFODION-1151
             Project: Apache Trafodion
          Issue Type: Bug
          Components: sql-exe
            Reporter: Sandhya Sundaresan
             Fix For: 2.0-incubating


When the RS goes down - for example killed by zookeeper due to out of memory conditions, the SQL query that was executing hangs and doesn't timeout for atleast an hour . 
But subsequent SQL queries immediately detect that RS is down and retirn an Hbase -705 error. 
The timeout values in JNI calls need to be investigated to see why the hang happens.
