> This is related to HDFS-7647
> DatanodeInfoWithStorage was introduced in org.apache.hadoop.hdfs.server.protocol package
whereas its base class, DatanodeInfo, is in org.apache.hadoop.hdfs.protocol
> Method signature change in LocatedBlock#getLocations() breaks downstream project(s) (such
as HBase) which may reorder DatanodeInfo's.
> DatanodeInfo is tagged @InterfaceAudience.Private
> DatanodeInfoWithStorage should have the same tag.
