Description

Please provide a way to limit only HDFS superusers the ability to assign HDFS Storage Policies to HDFS directories.

Currently, and based on Jira HDFS-7093, all storage policies can be disabled cluster wide by setting the following:
dfs.storage.policy.enabled to false
But we need a way to allow only HDFS superusers the ability to assign an HDFS Storage Policy to an HDFS directory.
