> when I use the eclipse on the windows to submit the job. and the applicationmaster throw
the exception:
> Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/mapreduce/v2/app/MRAppMaster

> Could not find the main class: org.apache.hadoop.mapreduce.v2.app.MRAppMaster.  Program
will exit.
> The reasion is :
> class Apps addToEnvironment function, use the

>       System.getProperty("path.separator");
> and will result the MRApplicationMaster classpath use the ";" separator.
> I suggest that nodemanger do the replace.
