---------------------------------------

Thanks [~mengqi] ...

The change in the LocatedBlock.getLocations() signature looks to have happened 
here, committed for hadoop-2.7, way back when.

DatanodeManager.sortLocatedBlocks sorts DatanodeInfos but not StorageIDs.

I'm bit baffled as to why I did not run into this testing – or why I don't see

(it'll be a few days I think...). Thanks.
