Kai Zheng commented on HDFS-8668:
---------------------------------
[~jingzhao] maybe you could take a look at this and let see if it sounds good?
Note I used *ElasticByteBufferPool* in favor of *DirectBufferPool* because we
need to deal with both on-heap ByteBuffer and off-heap ByteBuffer, as the issue
targeted. Thanks.
> Erasure Coding: revisit buffer used for encoding and decoding.

> For encoding and decoding buffers, currently some places use java heap
> ByteBuffer, some use direct byteBUffer, and some use java byte array. If
> the coder implementation is native, we should use direct ByteBuffer. This
> jira is to revisit all encoding/decoding buffers and improve them.
