Zhe Zhang commented on HDFS-10473:
----------------------------------

Thanks [~umamaheswararao] for proposing the idea. I agree that we can reject setting storage policies altogether at this stage, and revisit what policies can be allowed later.

> Currently 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.
