> Project: Hadoop Map/Reduce

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