Jing Zhao commented on HDFS-9534:
---------------------------------
Currently unspecified policy means using the default policy. Thus I do not
think we need an explicit policy named "UNSPECIFIED".
In the meanwhile, how should the semantic of the remove op look like? If we
have set a storage policy on "/foo", then should we allow the user to apply the
command on "/foo/bar" if bar is not associated with any explicit policy? Or
what if we have nested policy settings? I think we may need to list all the
scenarios and clearly define their semantic first.
> Add CLI command to clear storage policy from a path.

> The {{hdfs storagepolicies}} command has sub-commands for
> {{-setStoragePolicy}} and {{-getStoragePolicy}} on a path. However, there is
> no {{-removeStoragePolicy}} to remove a previously set storage policy on a
> path.
