Subject [jira] [Created] (TEZ-3036) Tez AM can hang on startup with no indication of error
Date Wed, 13 Jan 2016 21:52:40 GMT
Jason Lowe created TEZ-3036:
-------------------------------

             Summary: Tez AM can hang on startup with no indication of error
                 Key: TEZ-3036
                 URL: https://issues.apache.org/jira/browse/TEZ-3036
             Project: Apache Tez
          Issue Type: Bug
    Affects Versions: 0.7.0
            Reporter: Jason Lowe
            Priority: Critical


I've seen a couple of instances where the Tez AM fails to complete the startup sequence. 
It never gets around to registering with the ResourceManager, so the RM eventually times out
the attempt and starts another.  The subsequent attempts do the same.  There are no indications
in the logs that anything is wrong, rather it just seems to get stuck during startup then
a bit over 10 minutes later is killed.
