Subject [jira] [Created] (YARN-4767) Network issues can cause persistent RM UI outage
Date Fri, 04 Mar 2016 18:09:40 GMT
Daniel Templeton created YARN-4767:

             Summary: Network issues can cause persistent RM UI outage
                 Key: YARN-4767
                 URL: https://issues.apache.org/jira/browse/YARN-4767
             Project: Hadoop YARN
          Issue Type: Bug
          Components: webapp
    Affects Versions: 2.9.0
            Reporter: Daniel Templeton
            Assignee: Daniel Templeton
            Priority: Critical

If a network issue causes an AM web app to resolve the RM proxy's address to something other
than what's listed in the allowed proxies list, the AmIpFilter will 302 redirect the RM proxy's
request back to the RM proxy.  The RM proxy will then consume all available handler threads
connecting to itself over and over, resulting in an outage of the web UI.
