Arpit Agarwal updated HDFS-8345:
--------------------------------
Attachment: HDFS-8345.03.patch
Thank you Jing. I didn't see your latest comment last time.
The updated patch does something similar, it adds an interface
{{BlockStoragePolicySpi}} which can be used to query all storage policy
properties of interest to applications. {{BlockStoragePolicy}} inherits the
interface and remains private.
Also fixed a checkstyle issue, the remaining ones are unrelated to the patch.
> Storage policy APIs must be exposed via the FileSystem interface
