Tsz Wo (Nicholas), SZE commented on HDFS-4551:
----------------------------------------------
I see. We probably should do the same in branch-1.
> ... when the server has set io.file.buffer.size at 64kB ...
Do you mean 4KB? Or should we actually set the buffer size to 64KB?
> Change WebHDFS buffersize behavior to improve default performance
