[jira] [Created] (IMPALA-9199) Add support for single query retries on cluster membership changes

Sahil Takiar created IMPALA-9199:
------------------------------------

             Summary: Add support for single query retries on cluster membership changes
                 Key: IMPALA-9199
                 URL: https://issues.apache.org/jira/browse/IMPALA-9199
             Project: IMPALA
          Issue Type: Sub-task
            Reporter: Sahil Takiar
            Assignee: Sahil Takiar


If the cluster membership changes (either because the statestore detects that a node has left the cluster, or a node is added to the blacklist), then rather than cancelling / failing queries running on the target node, retry them.

This JIRA focuses on just retrying queries once.

There should be a query level option to control whether queries are retried or not.
