Jing Zhao commented on HDFS-8345:
---------------------------------
bq. Is there a reason not to include a convenience method that just takes a
BlockStoragePolicySpi object directly
Currently we still expect admins to set up policies first, and the users later
use names of existing policies to config files/directories. Directly using a
policy object in the API will allow users to pass self-created policies and
also bring in extra complexity for server side verification.
+1 on the 07 patch.
