Michael Ho updated IMPALA-7879:
-------------------------------
Issue Type: Improvement (was: Bug)
> Final profiles of queries should be reliably retrievable
> --------------------------------------------------------
>
> Key: IMPALA-7879
> URL: https://issues.apache.org/jira/browse/IMPALA-7879
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Affects Versions: Impala 3.0
> Reporter: Michael Ho
> Priority: Major
> Labels: query-lifecycle
>
> During a [code
> review|https://gerrit.cloudera.org/#/c/11964/1/tests/beeswax/impala_beeswax.py@206],
> [~tarmstrong] pointed out that there may be a problem with the query life
> cycle management which prevents the final profile from being accessible
> reliably for a query.
> In particular, the ExecSummary and Error sections are not added to the
> profile until a query is unregistered. At which point, the profile is
> archived. It's possible that the archive log rolls over before the profile is
> retrieved or that the profile archive log has been disabled. In which case,
> there is no way to get the final profile of a query. Ideally, the final
> profile should be available before query unregistration (e.g. once all
> backends have completed).
