> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Chen Liang

> FsDatasetImpl has this method
> {code}
> private void addVolume(Collection<StorageLocation> dataLocations,
> Storage.StorageDirectory sd) throws IOException
> {code}
> Parameter {{dataLocations}} was introduced in HDFS-6740, this variable was
> used to get storage type info. But HDFS-10637 has changed the way of getting
> storage type in this method, making dataLocations no longer being used at all
> here. We should probably remove dataLocations for a cleaner interface.
