Subject [jira] [Created] (YARN-6314) Potential infinite redirection on YARN log redirection web service
Date Thu, 09 Mar 2017 18:13:38 GMT
Xuan Gong created YARN-6314:

             Summary: Potential infinite redirection on YARN log redirection web service
                 Key: YARN-6314
                 URL: https://issues.apache.org/jira/browse/YARN-6314
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Xuan Gong
            Assignee: Xuan Gong

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.
