Arpit Agarwal commented on HDFS-8345:
-------------------------------------
Hi Sean, it's returned via DistributedFileSystem (it's in the Jira description).
Applications are using the storage policy APIs so I don't see the point of
making a breaking change unless necessary. Reclaiming the interface name is not
enough reason.
The checkstyle issues are not related to the patch. I will commit this shortly.
