      Description

      In HDFS-8319 Jing Zhao 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 Jing Zhao there are some good refactoring codes that would be incorporated here.
      As discussed open this to address the issues separately.
