Subject Re: How to get a list of running tasks in hbase shell?

TaskMonitor is probably relying on the fact that it's invoked inside of 
the RegionServer/Master process (note the maven module and the fact that 
it's a template file for the webUI).

You would have to invoke an RPC to the server to get the list of Tasks. 
I'm not sure if such an RPC already exists.
