> During HDFS balancing, after the target DN copied a block from the proxy DN, 
> it prints a log following the pattern below:
> *Moved BLOCK from BALANCER*
> This is somehow misleading, maybe we can improve the pattern like:
> *Copied BLOCK from PROXY DN, initiated by* *BALANCER*
>  
> An example log of target DN during balancing:
> 1. Wrong log printing before jira:
> {code:java}
