javax.management.RuntimeMBeanException: java.lang.NullPointerException

 

 

I verfied the override for this particular data node:

 

 

  </property>
  <!--'dfs.disk.balancer.enabled', originally set to 'true' (non-final), is overridden below by a safety valve-->
  <property>
    <name>dfs.disk.balancer.enabled</name>
    <value>false</value>
  </property>

 

 @pifta mentioned that there should be some error in the startup about race condition, but I dont see any kind of error except the NPE there. Also there was a suggestion that filled disks can cause this issue, but every data volume has at least 80GB available.

 

Thanks

And after 2 minutes (it was writing the same NPE error) suddenly "fixes" itself, and the DN starts..

So I am not sure now, is this because of the disable - or something else?

Removed the balancer override (so it is now true) and the DN is still ok. So I dont know what is the reason, but it is definitely not solved. I think under some conditions this can happen to anybody running on CDH5
