Zhijie Shen updated YARN-450:
-----------------------------

    Attachment: YARN-450_2.patch

Please see the newer patch, where ANY = "*" has been moved to ResourceRequest 
that is part of YARN API. Hence there's no need to add the dependency in 
pom.xml.

Btw, it seems that in protobuf, it is still unable to define static field. See 
https://code.google.com/p/protobuf/issues/detail?id=60
                
> Define value for * in the scheduling protocol

> 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.
