Quanlong Huang commented on IMPALA-8763:
----------------------------------------
I think somehow the mtime in the catalogd side introduced by IMPALA-6670 is
broken, which should be fixed in this JIRA.
> Dedicated executors not invalidating stale LibCache entries
> -----------------------------------------------------------
>
> Key: IMPALA-8763
> URL: https://issues.apache.org/jira/browse/IMPALA-8763
> Project: IMPALA
> Issue Type: Bug
> Reporter: Quanlong Huang
> Priority: Major
>
> This is a follow-up Jira for IMPALA-8486. Dedicated executors won't receive
> any catalog updates since they don't subscribe to the catalog-update topic.
> This causes them unable to notice whether a libCache entry is stale.
> We may need to introduce a new topic for the dedicated executors to subscribe
> to invalidate the stale libCache entries.
