Zhe Zhang commented on HDFS-8347:
---------------------------------
My point was that encoding unit size doesn't affect the end result (the byte
content of encoded data). Therefore it shouldn't have any relationship to the
decoding unit to use.
> Erasure Coding: whether to use chunkSize as the to decode buffersize for
> Datanode striped block reconstruction.

> Currently decode buffersize for Datanode striped block reconstruction is
> configurable and can be less or larger than chunksize, it may cause issue for
> Hitchhiker which may require encode/decode using same buffersize.
