got it the culprit was apaches website frm whr i copied the secnamenodeaddrs
 
http://hadoop.apache.org/docs/r0.23.0/hadoop-yarn/hadoop-yarn-site/Federation.html#Configuration
 
here secondary.http-address.ns1 shud be used instead of  secondaryhttp-address.ns1
 
<property>
    <name>dfs.namenode.secondaryhttp-address.ns1</name>
    <value>snn-host1:http-port</value>
  </property>
