Re: Namenode is failing with expception to join
Manish,

you stop HDFS then start HDFS on the standby name node right?

please looked at https://issues.apache.org/jira/browse/HDFS-5058

there are two solutions:
1) start HDFS on the active name node, nor SBN
2) copy {namenode.name.dir}/* to the SBN

I advice #1.
