Thanks a lot, Peter. I found another way to bring it up again,
As I thought there should be some incorrect status stored in the graph, maybe start up the master instance in Non-HA mode can rectify the status. I tried and that works. Now the HA cluster is running normally. However, to prevent it happen again, I will setup a 3-node zk cluster.
