Upgraded APIs: Flink (0.8) and HBase (0.98.x) + profiles

I had to create an hadoop.core.version variable to manage the fact that cloudera has different versions for hadoop-core and hadoop-common..
What I dislike about the profile is that its very specific about the version. We basically need to manually maintain the CDH versions and force users into specific CDH versions.

Would it be possible to add the `<dependencyManagement>` section with the hadoop-core dependency into the `hadoop2` profile and set the hadoop.core.version to hadoop-2.2.0 by default? 
This way users could actually specify their specific hadoop versions if they want to build flink against a particular CDH build?
