Konstantin is right.
Anyway, did you add namenode address to file masters under conf directory?
I think only when I need this node to be a secondary namenode that I
will do this.

I'm not sure I get this.
1. If you format the filesystem (which I thought is usually executed on the
master node, but anyway)
don't you erase all your data?
2. I guess I need to add the new machine to the conf/slaves file,
but then I run the start-all.sh again from the master node while my cluster
You just start the new data-node as the cluster is running using
bin/hadoop datanode
The configuration on the new data-node should be the same as on other nodes.
The data-node should join the cluster automatically.
Formatting will destroy your file system.

It is really different from what you said that on my cluster, and
performing format command will not destroy the file system. And if I do
not perform format command on datanode, the datanode will not be able to
find my the master.
Hopefully anybody can tell me the reason.
