    Description

      Currently some of existing storage policies are not suitable for striped layout files.
      This JIRA proposes to reject setting storage policy on striped files.

      Another thought is to allow only suitable storage polices like ALL_SSD.
      Since the major use case of EC is for cold data, this may not be at high importance. So, I am ok to reject setting storage policy on striped files at this stage. Please suggest if others have some thoughts on this.

      Thanks zhz for offline discussion on this.
