Resolution: Implemented
> Track time of last statistics update in metadata
> ------------------------------------------------

> Key: IMPALA-6131
> URL: https://issues.apache.org/jira/browse/IMPALA-6131
> Project: IMPALA
> Issue Type: Sub-task
> Components: Backend, Frontend
> Reporter: Lars Volker
> Assignee: Csaba Ringhofer
> Priority: Major
> Labels: ramp-up
>
> Currently we (ab-)use {{transient_lastDdlTime}} to track the last update time
> of statistics. Instead we should introduce a separate counter to track the
> last update. With that we should also remove all occurrences of
> {{catalog_.updateLastDdlTime()}} from {{CatalogOpExecutor}} and fall back to
> Hive's default behavior.
