----------------------------------------------
Summary: Investigate exec summary behavior
Key: IMPALA-5783
URL: https://issues.apache.org/jira/browse/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.
