      Description

      Hadoop client often throws exception with "java.io.IOException: Cannot initialize Cluster. Please check your configuration for mapreduce.framework.name and the correspond server addresses".

      This is a misleading and generic message for any cluster initialization problem. It takes a lot of debugging hours to identify the root cause. The correct error message could resolve this problem quickly.

      In one such instance, Oozie log showed the following exception while the root cause was CNF that Hadoop client didn't return in the exception.

       JA009: Cannot initialize Cluster. Please check your configuration for mapreduce.framework.name and the correspond server addresses.
