Bikas Saha commented on YARN-450:
---------------------------------

There is already way too much in configuration according to many folks. configuration also does not sound like a good place for something that is api. also see YARN-444.

> The ResourceRequest has a string field to specify node/rack locations. For the cross-rack/cluster-wide location (ie when there is no locality constraint) the "*" string is used everywhere. However, its not defined anywhere and each piece of code either defines a local constant or uses the string literal. Defining "*" in the protocol and removing other local references from the code base will be good.
