-cdh4 HA fencing fails when the other node is down

I am trying to setup HA Namenode using cdh4, zkfc.
It works great when I kill -9 the active namenode.
But if I reboot/shutdown the host with active namenode. Failover fails.
The ZKFC complains fencing not succesful.
It has no route to host exception.
Is this expected ?
I looked into mailing list.
It seems that the fix is to move away from zkfc and use quorum based
But, this should be a pretty common requirement and I would think
there will be a solution for this scenario (With zkfc).
Please guide me/point me to solution.
