dhruba borthakur resolved HADOOP-1605.
--------------------------------------
Resolution: Won't Fix
Fix Version/s: (was: 0.15.0)
System administrators already employ some means to detect if a server is
disappears, and restarts it automatically if need be. Especially because they
have to administer may different types of servers/applications. I am closing
this issue as "won't fix".
