Smita, Any chance you can print the value of containers waiting and total before the exception.
From http://svn.apache.org/viewvc/hadoop/common/branches/branch-2.4.1/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-client/src/main/java/org/apache/hadoop/yarn/client/api/impl/AMRMClientImpl.java?view=markup around line 207, it looks like your progress value is getting negative.
