> 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.
