> 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}
