Attachment: (was: HDFS-11361-HDFS-7240.001.patch)
> Block Storage : add cache interface
> -----------------------------------
>
> Key: HDFS-11361
> URL: https://issues.apache.org/jira/browse/HDFS-11361
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: hdfs
> Reporter: Chen Liang
> Assignee: Chen Liang
>
> To be able to get better performance, it would greatly helpful if cblock is
> able to cache data locally. More specifically, ideally, clients' read/write
> should be performed on the locally disk cache, while threads are pushing and
> retrieving data in backend.
> This JIRA takes the first step by defining interfaces for the local cache.
> This allows us to implement caches with a baseline and makes the unit tests a
> lot easier.
