> Key: HADOOP-12060
> URL: https://issues.apache.org/jira/browse/HADOOP-12060
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: io
> Reporter: Kai Zheng
> Assignee: Kai Zheng
> Fix For: HDFS-7285
>
> Attachments: HADOOP-12060-HDFS-7285-v1.patch,
> HADOOP-12060-HDFS-7285-v2.patch, HADOOP-12060-HDFS-7285-v3.patch
>
>
> 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.
