Attached patch v3 to address the checkstyle issues as well as removing minor 
duplication from HDFS-14138.

The last jenkins run looks good - the two failed tests do not seem to be

> When we re-queue RPC call, the {{internalQueueCall}} will potentially throw 
> exceptions (e.g., RPC backoff), which is then swallowed. This will cause the 
> RPC to be silently discarded without response to the client, which is not 
> good.
