----------------------------------

             Summary: Address some issues related to ByteBuffer type input/output buffers
for raw erasure coders
                 Key: HADOOP-12060
                 URL: https://issues.apache.org/jira/browse/HADOOP-12060
             Project: Hadoop Common
          Issue Type: Sub-task
            Reporter: Kai Zheng
            Assignee: Kai Zheng


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.
