> # The usage of following two variables is unnecessary. We can remove them to
> make code a bit brief.
> {quote}
> private final boolean hasStorageIDs;
> private final boolean hasStorageTypes;
> {quote}
> # In HDFS-7647, no need to modify {{LocatedBlock#getStorageTypes}} and
> {{LocatedBlock#getStorageIDs}}, we just need to update the cached
> {{storageIDs}} and {{storageTypes}} after *sort*.
> # Another thing is we'd better setSoftwareVersion when constructing
> {{DatanodeInfoWithStorage}} from {{DatanodeInfo}}
