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..
No, haven't tried to reproduce it. 
Is the Configuration object empty (no keys and values) or is the object just null?
I can also open an issue, just wanted to make sure that we do not forget about it.
