Kai Zheng commented on HDFS-8668:
---------------------------------
Thanks [~hitliuyi] for the issue and assigning it to me. As some part isn't
easy and we have to change to use ByteBuffer from bytes array first, some part
couples with buffer pool stuffs, I break this whole consideration into smaller
issues and will work on them.
> Erasure Coding: revisit buffer used for encoding and decoding.

> Key: HDFS-8668

> Project: Hadoop HDFS
> Issue Type: Sub-task
> Reporter: Yi Liu
> Assignee: Kai Zheng
>
> 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.
