Subject [jira] [Created] (HAWQ-1324) Query cancel cause segment to go into Crash recovery
Date Mon, 13 Feb 2017 07:02:41 GMT
Ming LI created HAWQ-1324:
-----------------------------

             Summary: Query cancel cause segment to go into Crash recovery
                 Key: HAWQ-1324
                 URL: https://issues.apache.org/jira/browse/HAWQ-1324
             Project: Apache HAWQ
          Issue Type: Bug
            Reporter: Ming LI
            Assignee: Ed Espino


A query was cancelled due to this connection issue to HDFS on Isilon. Seg26 then went into
crash recovery due to a INSERT query being cancelled. What should be the expected behaviour
when HDFS becomes unavailable and a Query fails due to HDFS unavailability.
Below is the HDFS error
