> Prevent Coordinator::UpdateFilter() running after query exec resources are
> released
> -----------------------------------------------------------------------------------
>
> Key: IMPALA-6153
> URL: https://issues.apache.org/jira/browse/IMPALA-6153
> Project: IMPALA
> Issue Type: Bug
> Components: Backend
> Reporter: Sailesh Mukil
> Assignee: Pooja Nilangekar
> Priority: Major
> Labels: query-lifecycle, runtime-filters
>
> Coordinator::UpdateFilter() and CoordinatorBackendState::PublishFilter() run
> independent of the lifecycle of any fragment instance. This is problematic
> during query teardown.
> Specifically we should not release resources for a query if any one of those
> above functions are still running for that query and we also should not not
> start running the above methods after resources are released for the query.
> Also, the 'rpc_params' in UpdateFilter() could potentially hold large amounts
> of untracked memory, so we should track it.
