[jira] [Created] (MAPREDUCE-4052) Windows eclpise can not submit the job

Windows eclpise can not submit the job
--------------------------------------

                 Key: MAPREDUCE-4052
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4052
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: job submission
    Affects Versions: 0.23.1
         Environment: client on the Windows, the the cluster on the suse
            Reporter: xieguiming


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
Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.mapreduce.v2.app.MRAppMaster
        at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
        at java.security.AccessController.doPrivileged(Native Method)
        at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:307)
        at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
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
private static final String SYSTEM_PATH_SEPARATOR =
      System.getProperty("path.separator");

and will result the MRApplicationMaster classpath use the ";" separator.

I suggest that nodemanger do the replace.
