Tsz Wo Nicholas Sze commented on HDFS-6809:
-------------------------------------------
The test failures were mostly due to UnknownHostException. I guess the Jenkins
machine has some problems.
The findbugs warning is an existing bug. I will fix it in my next patch as
well.
> Move some Balancer's inner classes to standalone classes
