      Description

      We had a balancer that had not made any progress for a long time. It turned out it was repeatingly asking Namenode for a partial block list of one datanode, which was done while the balancer was running.

      NameNode should notify Balancer that the datanode is not available and Balancer should stop asking for the datanode's block list.
