Zhe Zhang commented on HDFS-8347:
---------------------------------
Thanks Yi for finding out the error. AFAIU the end result of encoding a set of
10-byte chunks should be the same as encoding individual bytes one by one. Not
quite sure how Hitchhiker changes the story.
> 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.
