> Ozone : add read/write random access to Chunks of a key
> -------------------------------------------------------
>
> Key: HDFS-11939
> URL: https://issues.apache.org/jira/browse/HDFS-11939
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Reporter: Chen Liang
> Assignee: Chen Liang
> Attachments: HDFS-11939-HDFS-7240.001.patch
>
>
> In Ozone, the value of a key is a sequence of container chunks. Currently,
> the only way to read/write the chunks is by using ChunkInputStream and
> ChunkOutputStream. However, by the nature of streams, these classes are
> currently implemented to only allow sequential read/write.
> Ideally we would like to support random access of the chunks. For example, we
> want to be able to seek to a specific offset and read/write some data. This
> will be critical for key range read/write feature, and potentially important
> for supporting parallel read/write.
> This JIRA tracks adding support by implementing FileChannel class on top
> Chunks.
