It seems like all the node woker processes are working as if it is executing a new copy of the same application. But would like to keep some variables that are shared by all node workers (child processes) in node cluster. Is there a simple way to do this?

All worker processes are indeed new copies of your application. Each worker is a full featured process created with child_process.spawn.
So no, they don't share variables. And it's probably best this way.
If you want to share information between worker processes (typically sessions) you should look into storing these information in a database.

If you're ready to go node all the way, you could use something like dnode to have your workers ask the master process for data.
