Suraj Menon commented on HAMA-585:

Thanks Chiahung. This is a big task that you removed from my to-do list! 
I think this should be a part of HAMA-505. I would be merging this to my current changes for

I just perused through your patch. Can the function, moveToBlackList(String host) in BSPMaster
call the task recovery logic or should I keep a Thread watching blackList? I don't know how
the call to blacklist node is going to be made. The recovery logic would run if any tasks
were found running on the blacklisted GroomServer.
