This is not right. Whats supposed to happen is that the first
master's znode is meant to expire in zk and then the second master
assumes the original's role. Did the first master come up fine. You
waited long enough for the first master's znode to expire?
What version of hbase?
I am using the HBase 0.90.1 How much time it will take to expire the first
master Znode expire ?

Yes. I'd think so.

to connect to the backup master ?
They are trying to connect to the first master and will continue so
until the master's address is updated in zk when the secondary assumes
master role.
