Subject [jira] [Created] (IMPALA-5783) Investigate exec summary behavior
Date Wed, 09 Aug 2017 16:18:00 GMT
Thomas Tauber-Marshall created IMPALA-5783:

             Summary: Investigate exec summary behavior
                 Key: IMPALA-5783
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
    Affects Versions: Impala 2.10.0
            Reporter: Thomas Tauber-Marshall

A recent investigation into a flaky test, IMPALA-5708, brought up the issue that the exec
summary may not always be filled in for certain queries, even if the query is FINISHED.

For example, a query with a limit or subquery that internally cancels some fragments because
they are no longer needed may never update the exec summary with info from those fragments.

We should investigate what guarantees we can make about when the exec summary will be present
and add automated tests to check these guarantees.
