storm netty connection failed error

[이승진 <sw...@navercorp.com>]

Hi all,
 
I just upgraded storm to 0.9.2-incubating (previously using 0.9.0.1), launched a simple topology, and got an error related to Netty
 
Do I have to prepare Netty seperately or is there any reason of exception below?
 
Any comments would help, thanks in advance.
