    Description

      When Balancer is running, it is found that there are many logs, such as

      INFO  balancer.Dispatcher (Dispatcher.java:markMovedIfGoodBlock(306)) - No striped internal block on source xxx:50010:SSD, block blk_-xxx_xxx size=982142783. Skipping.
      

      these logs show that Balancer cannot to balancer SSD type sourceļ¼Œ and it causes that Balancer will frequently get blocks from NN through getBlocks RPC.

      The main reason is the storage type in the current Source is SSD, but now getBlocks obtains all list of blocks belonging to datanode, so need add the parameter storage type for getBlocks method
