ResourceManager fails to start (cdh 5.5.2): HTTP server failure

New Contributor

Similar to this previously posted problem, I am unable to start my ResourceManager.  This started after I upgraded my box (Ubuntu 12.04 to 14.04), which most likely also upgrade CDH to 5.5.2.

As suggested in the above post, I tried enabling debugging (added ",console" to /etc/hadoop/conf/, but I still don't see any reasons this is failing.


Here's my /var/log/hadoop-yarn/yarn-yarn-resourcemanager-elgordo.log file:

There's a Hadoop JIRA bug fixed in Hadoop 2.7 that sounds like the fix I need (; but I don't see why this is failing for me, but not for everyone else.  Is there a configuration change that I can make to avoid this particular Hadoop bug?  


There's an option Cloudera JIRA issue that looks similar: (no replies on it though).
