Hairong Kuang commented on HADOOP-5672:
---------------------------------------
1. better set the initial value of maxSizeToMove to be MAX_SIZE_TO_MOVE;
2. since maxSizeToMove is a field of Balancer, there is no need to change any
method signature.
3. description of the property dfs.balancer.maxSizeToMove shoud specify that
this is the max number of bytes to move per iteration.
> Use custom MAX_SIZE_TO_MOVE value Balancer
