Description

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.
