Pavel Ganelin commented on MAPREDUCE-4052:
------------------------------------------
It is still an issue with hadoop 2.2.
The following ugly workaround can be used on the client side without modifying
the hadoop jar files:
{code}
{
Field field = Shell.class.getDeclaredField("WINDOWS");
field.setAccessible(true);
Field modifiersField = Field.class.getDeclaredField("modifiers");
modifiersField.setAccessible(true);
modifiersField.setInt(field, field.getModifiers() &
~Modifier.FINAL);
field.set(null, false);
}
{
Field field = java.io.File.class.getDeclaredField("pathSeparator");
field.setAccessible(true);
Field modifiersField = Field.class.getDeclaredField("modifiers");
modifiersField.setAccessible(true);
modifiersField.setInt(field, field.getModifiers() &
~Modifier.FINAL);
field.set(null, ":");
}
{code}

> 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 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.
