[jira] [Created] (IMPALA-6153) Do not unregister query if runtime filters are being aggregated

Sailesh Mukil created IMPALA-6153:
-------------------------------------

             Summary: Do not unregister query if runtime filters are being aggregated
                 Key: IMPALA-6153
                 URL: https://issues.apache.org/jira/browse/IMPALA-6153
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
            Reporter: Sailesh Mukil
            Priority: Major


Coordinator::UpdateFilter() and CoordinatorBackendState::PublishFilter() run independent of the lifecycle of any fragment instance. This is problematic during query teardown.

Specifically we should not unregister a query if any one of those above functions are still running for that query. Also, the 'rpc_params' in UpdateFilter() could potentially hold large amounts of untracked memory, so we should track it.
