Hi Praveen, Can you please look at the RM logs and check if there are any errors/exceptions. I ran into a similar issue when my RM was down.
Also, the defaults are present at http://svn.apache.org/repos/asf/hadoop/common/branches/MR-279/mapreduce/yarn/yarn-server/yarn-server-common/src/main/resources/yarn-default.xml .
