> Should add diagnostics in DAGAppMaster when recovery error happens, otherwise
> AM is shutdown and the next dag submission will just throw
> SessionNotRunningException which would confuse users.
> {code}
> if (this.historyEventHandler.hasRecoveryFailed()) {
> LOG.warn("Recovery had a fatal error, shutting down session after" +
> " DAG completion");
> sessionStopped.set(true);
> }
> {code}
