Thanks, this makes a lot of sense.

We should merge this for Flink 1.1.1
For Flink 1.2.0, we should actually fix the root issue, which is that the hadoop1 artifact has a scala suffix even though it does not need one. I think this was introduced by accident.

I merged this into the 1.1 release branch.
For the 1.2 releases, we should use this fix: #2343
