Subject [jira] [Created] (DRILL-2650) Cancelled queries json profile shows query end time occurs before fragments end time

             Summary: Cancelled queries json profile shows query end time occurs before fragments
end time 
                 Key: DRILL-2650
                 URL: https://issues.apache.org/jira/browse/DRILL-2650
             Project: Apache Drill
          Issue Type: Bug
          Components: Client - HTTP
    Affects Versions: 0.9.0
            Reporter: Krystal
            Assignee: Jason Altekruse


I have a query that was successfully cancelled.  The query start and end time is as follows:
"type": 1,
    "start": 1427839192049,
    "end": 1427839194966,

This translates to a query duration of about 3 seconds.  However, the duration of the query's
fragments are much longer up to more than 6 seconds.  Here is an entry for majorFragmentId=0
with a duration of 6.6 seconds:
 "startTime": 1427839192796,
 "endTime": 1427839199408,

8 out of 11 major fragments have duration greater than the query itself.  To an end user,
this is confusing and does not make sense.  We should wait for all of the major fragments
to be completely cancelled before updating the the "end" time of the query.
