I have an Map reduce program that is running successfully in standalone(Ecllipse) mode but while trying to run the same MR by exporting the jar in cluster. It is showing null pointer exception like this,

  13/06/26 05:46:22 ERROR mypackage.HHDriver: Error while configuring run method. 
  java.lang.NullPointerException

I double checked the run method parameters those are not null and it is running in standalone mode as well..
