> DAG submission failure can also happen in environments where AM container died causing
DNS issues. DAG submissions are safe to retry as the DAG hasn't started execution yet. There
are retries at getSession and submitDAG level individually but some submitDAG failure has
to retry getSession as well as AM could be unreachable, this can be handled in re-execution
plugin.
> There is already AM loss retry execution plugin but it only handles managed AMs. It can
be extended to handle unmanaged AMs as well.
