org.apache.hadoop.hdfs.server.protocol.BalancerBandwidthCommand
Balancer bandwidth command instructs each datanode to change its value for the max amount of network bandwidth it may use during the block balancing operation. The Balancer Bandwidth Command contains the new bandwidth value as its payload. The bandwidth value is in bytes per second.

          cmds.add(new KeyUpdateCommand(accessTokenHandler.exportKeys()));
          nodeinfo.needKeyUpdate = false;
        }
        // check for balancer bandwidth update
        if (nodeinfo.getBalancerBandwidth() > 0) {
          cmds.add(new BalancerBandwidthCommand(nodeinfo.getBalancerBandwidth()));
          // set back to 0 to indicate that datanode has been sent the new value
          nodeinfo.setBalancerBandwidth(0);
        }
        if (!cmds.isEmpty()) {
          return cmds.toArray(new DatanodeCommand[cmds.size()]);
