fuchaohong updated HDFS-17872:
------------------------------
    Description: 
dfs.disk.balancer.block.tolerance.percent
The tolerance percent specifies when we have reached a good enough value for 
any copy step. For example, if you specify 10% then getting close to 10% of the 
target value is good enough.
 
目前只在plan中传递了maxDiskErrors、bandwidth,希望

> DiskBalancer: Plan command support with tolerancePercentage.
