I read Hadoop ver 3 document about disk balancer and it said

"Diskbalancer is a command line tool that distributes data evenly on all disks of a datanode.
This tool is different from Balancer which takes care of cluster-wide data balancing."

I really dont know whats difference between 'balancer' and 'disk balancer' yet.
Could you explain what is it?
Thank you!

Balancer deals with internodes data balancing present in multiple datanodes present in the cluster whereas disk balancer deals with data present disks of a single datanode.
