Chen Liang updated HDFS-11537:
------------------------------
Attachment: HDFS-11537-HDFS-7240.005.patch
post v005 patch to resolve the findbug, checkstyle and javadoc warnnings. Some
of the checkstyle warnings were still about the hidden fields of setting
method, probably because the setting methods are for builder and thus not
recognized as settings. These warnnings are ignored.

> This JIRA adds the cache layer. Specifically, this JIRA implements the cache
> interface in HDFS-11361 and adds the code that actually talks to containers.
> The upper layer can simply view the storage as a cache with simple put and
> get interface, while in the backend the get and put are actually talking to
> containers. This is a critical part to the cblock performance.
