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.`
Currently, only *{{maxDiskErrors}}* and *{{bandwidth}}* are passed in the plan,
and it is expected that *{{tolerancePercentage}}* can also be propagated to the
DataNode.
