-Xmx128m
-Xmx128m
-Dhadoop.log.dir=/home/nn2/logs
-Dhadoop.log.file=hadoop-root-namenode-HOST-xx-xx-xx-105.log
-Dhadoop.home.dir=/home/nn2/
-Dhadoop.id.str=root
-Dhadoop.root.logger=INFO,RFA
-Dhadoop.policy.file=hadoop-policy.xml
-Djava.net.preferIPv4Stack=true
-Dhadoop.security.logger=INFO,RFAS
-Dhdfs.audit.logger=INFO,NullAppender
-Dhadoop.security.logger=INFO,RFAS
-Dhdfs.audit.logger=INFO,NullAppender
-Dhadoop.security.logger=INFO,RFAS
-Dhdfs.audit.logger=INFO,NullAppender
-Xdebug
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8001

In above VM argumants -Xmx1000m will be Overridden by -Xmx128m.
BTW Other duplicate arguments wont harm
