Zhe Zhang commented on HDFS-8347:
---------------------------------
BTW in client decoding (HDFS-7678) I've been trying to create a true unit test
isolated from codec and output stream. {{testPreadWithDNFailure}} fakes blocks
on DNs, and manipulates expected content so as long as the client decoding
logic itself is correct, test will pass.
> 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.
