-------------------------------
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.
