------------------------------------------
Hi [~brahmareddy],
Thanks for pointing me to HDFS-11177.
As you have pointed out, this bug is support storage policies command with HDFS
federation.
This bug will add support to resolve Viewfs based paths to HDFS ones and then
apply storage policy commands on them.
