> In HDFS-8319 [~jingzhao] raised some issues about ByteBuffer type input/output buffers
for raw erasure coders:
> * Should support ByteBuffers originated from {{ByteBuffer#slice}} calls;
> * Should clearly spec in Javadoc that no mixing of on-heap buffers and direct buffers
are allowed, and with necessary checking codes ensuring the same type of buffers are used.
> In HDFS-8319 patch by [~jingzhao] there are some good refactoring codes that would be
incorporated here.
> As discussed open this to address the issues separately.
