Roman Shaposhnik commented on BIGTOP-761:
-----------------------------------------

+1 on the part of the patch that fixes where YARN libs are picked from.

I'm a little bit hesitant to commit the logic that takes old and new style into 
account. Historically in Bigtop we only care about one particular version of 
each component that's part of the BOM. Now that we've switched to Hadoop 
2.0.2-alpha I don't think there's any reason for us to look back.

Thoughts?
