> When Balancer is running, it is found that there are many logs, such as
> {code:java}
> INFO balancer.Dispatcher (Dispatcher.java:markMovedIfGoodBlock(306)) - No
> striped internal block on source xxx:50010:SSD, block blk_-xxx_xxx
> size=982142783. Skipping.
> {code}
> these logs show that Balancer cannot to balancer SSD type sourceļ¼ 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
