>
> In YARN-6113, we have added a re-direct NM web service to get container logs
> which could cause the potential infinite redirection.
> It can happens when:
> * Call AHS web service to get a running/finished AM container log for a
> running application.
> * AHS web service would re-direct the request the specific NM given the
> application is still running. And the NM would handle the request
> * If the log file we requested has already been aggregated and deleted from
> NM, the NM would re-direct the request back to AHS.
> In this case, we would do step 2 and step 3 infinite times.
