> this issue is similar to HDFS-14535.
> {code:java}
> public static BlockReader newBlockReader(String file,
>     ExtendedBlock block,
>     Token<BlockTokenIdentifier> blockToken,
>     long startOffset, long len,
>     boolean verifyChecksum,

>     PeerCache peerCache,
>     CachingStrategy cachingStrategy,
>     int networkDistance) throws IOException {
>   // in and out will be closed when sock is closed (by the caller)
>   final DataOutputStream out = new DataOutputStream(new BufferedOutputStream(
>       peer.getOutputStream()));
>   new Sender(out).readBlock(block, blockToken, clientName, startOffset, len,
>       verifyChecksum, cachingStrategy);
> }
> public BufferedOutputStream(OutputStream out) {
>     this(out, 8192);
> }
> {code}
> Sender#readBlock parameter( block,blockToken, clientName, startOffset, len, 
> verifyChecksum, cachingStrategy) could not use such a big buffer.
> So i think it should reduce BufferedOutputStream buffer.
