  <p>They do give the solution for single datanode imbalace.But I still got question.</p>
  
  <p>Lets assume I have 2 disks: "/disk1" and "/disk2".In each disk, there are data directory "./data".So there are 2 data directory "/disk1/data" and "/disk2/data".And here is the question:</p>
  
  <p>Could I move <strong>blocks and meta pairs</strong> in "/disk1/data/current" to "/disk2/data/current/"?</p>
