Vinod Kumar Vavilapalli commented on MAPREDUCE-4052:
----------------------------------------------------

Patch looks fine overall, some review comments on the MR part of the patch
 - TestMapReduceChildJVM.envVar can be removed.
 - MAPREDUCE_CROSS_PLATFORM_APP_SUBMISSION -> 
MAPREDUCE_APP_SUBMISSION_CROSS_PLATFORM, 
"mapreduce.cross-platform.app-submission" -> 
"mapreduce.app-submission.cross-platform". Similarly the name of the default 
constant too.
 - The default for the above config should be false for compatibility
 - Given that, fix the description of mapreduce.application.classpath in 
mapred-default.xml
 - Add the new config in mapred-default.xml
 - Cannot rename MRJobConfig.DEFAULT_MAPREDUCE_APPLICATION_CLASSPATH for 
compatibility
 - MRJobConfig.DEFAULT_MAPREDUCE_APPLICATION_CLASSPATH_CROSS_ENV and 
DEFAULT_MAPREDUCE_APPLICATION_CLASSPATH_CLIENT_ENV also to be renamed in line 
with the YARN constant renames.
 - Fix their javadoc too to refer to cross-platform.
 - There are still some usages of yarn.util.Apps. They are not intended?

> Could not find the main class:

> 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.
