Description

Currently the mapred-default.xml has "mapreduce.application.classpath" entry set to
$HADOOP_MAPRED_HOME/share/hadoop/mapreduce/,$HADOOP_MAPRED_HOME/share/hadoop/mapreduce/lib/
which is problematic on Windows since the path does not work on Windows OS.

Additionally, the yarn-default.xml has "yarn.application.classpath" entry that has similar problem, and is currently being tracked by YARN-1138
