@nilday I was thinking that you didn't really need to change your code much
at all, and still leave it in java. I would be perfectly happy to have your
scheduler take a scheduler as input to the constructor and wrap it. Then you
could modify one small place in nimbus.clj.
https://github.com/apache/storm/blob/master/storm-core/src/clj/org/apache/storm/daemon/nimbus.clj#L116-L132
to wrap the returned scheduler in your implementation.
The UI work can be a follow on JIRA, but I would like to see at least a
metric put in place that shows the number of blacklisted nodes so we can at
least set up alerts on it.
