Zhaobo Huang updated HDFS-17688:
--------------------------------
Description:
It is used to limit the number of nodes that exceed the cluster average but are
below threshold.
During each round of balancer operation, sometimes does not focus on nodes that
are greater than the average value(AboveAvgUtilized), but instead prioritizes
processing nodes that exceed the threshold(OverUtilized), we can set
'limitAboveAvgUtilizedNum' value to 0.
> Add Option to limit Balancer aboveAvgUtilized nodes num in each iteration.
