Hadoop 2.6.0: main error "starting MRAppMaster" after installation

Question

I just started working with Hadoop 2.

After installing with the basic configurations, I always did not run any examples. Has anyone seen this problem and please help me?

And the error is something like

Error starting MRAppMaster
java.lang.RuntimeException: java.lang.reflect.InvocationTargetException

This is a magazine.
