Chen Liang commented on HDFS-11537:
-----------------------------------
The failed tests were caused by "address already in use" error. The tests
passed in local runs so the fails seem to be specific to this particular
Jenkins run. The checkstyle warnings were about the setting method, as
mentioned above.

> 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.
