> HDFS-9534 added new API in FileSystem to unset the storage policy. Once policy is unset
blocks should move back to the default storage policy.
> Currently mover is not moving file blocks which have zero storage ID
> {code}
>       // currently we ignore files with unspecified storage policy
>       if (policyId == HdfsConstants.BLOCK_STORAGE_POLICY_ID_UNSPECIFIED) {
>         return;
>       }
> {code}
