HDFS load balancing + how to replace the round robin with org.apache.hadoop.hdfs.server.datanode.fsdataset.AvailableSpaceVolumeChoosingPolicy

hi all

 

we have HDP cluster version 2.6.5 , with ambari 2.6.2.2

as I understands the default load HDFS balancing is round robin

 

is it possible to change the round robin with org.apache.hadoop.hdfs.server.datanode.fsdataset.AvailableSpaceVolumeChoosingPolicy ?

 

 

if yes then how to implemented it in ambari HDFS configuration
