>             Project: Hadoop HDFS
>          Issue Type: Improvement
>            Reporter: Haiyang Hu

> DataXceiver#readBlock code is:
> {code:java}
> ...
>   read = blockSender.sendBlock(out, baseStream, null); // send data
> ..
> {code}
> Current DataXceiver#readBlock doesn't throttler, maybe we can support 
> throttle for reading block satisfied catering for specific scenarios.
> Default read throttler value is still null.
