Hi Bobby,
   I am using Storm 1.1.0. Oh, I forgot. F.Y.I, before I turn on the feature, 
the section is displayed. However, according to kishorvpatil's 
 , it shouldn't. Is this a problem? In addition, in the first place, I forgot 
to sync storm.yaml to all worker nodes. After sync, the Storm cluster can be 
started but topologies can not run. So I checked logs and found there were a 
lot of errors about Netty. Connection is refused to some workers. And some of 
my workers have OpenJDK installed. I do not know whether there is causal link 
here. If I want to use a different profiler, how to set 
worker.profiler.command? Set to path relative to $JAVA_HOME/bin? And

I'm not sure.  That should be enough.  There might be a bug in the ui code 
though.  What version of storm are you using?  Also did you select any workers 
to profile?

buttons in Profiling and Debugging section are disabled. Below is the related 
configuration. If my configuration is wrong, would somebody tell me how to do
