ERROR rised during backup node starting
Hi ALL

 I am testing my backup node(CDH4.1.2).After I setup the neccessory
settings,i started the backup node.
 Everything went well,except for an ERROR had risen[1].

 What is the problem, and what is the lib.MethodMetric  used for ?
 I also noticed the Bad state: UNINITIALIZED.I wondered  when the
UNINITIALIZED  state could come out?

 Any help will be appreciated.
