Arpit Agarwal updated HDFS-7647:
--------------------------------
Description: ,m.t, the DatanodeInfos and StorageIDs/StorageTypes are
mismatched. The method is called by FSNamesystem.getBlockLocations(), so the
client will not know which StorageID/Type corresponds to which DatanodeInfo.
(was: DatanodeManager.sortLocatedBlocks() sorts the array of DatanodeInfos
inside each LocatedBlock, but does not touch the array of StorageIDs and
StorageTypes. As a result, the DatanodeInfos and StorageIDs/StorageTypes are
mismatched. The method is called by FSNamesystem.getBlockLocations(), so the
client will not know which StorageID/Type corresponds to which DatanodeInfo.)
