    Did you intend to directly call `VersionInfo`, or should we maybe do this with reflection
instead?

> Currently, all Flink releases ship with Hadoop 2.3.0 binaries.
> The big Hadoop distributions are usually not relying on vanilla Hadoop releases, but
on custom patched versions.
> To provide the best user experience, we should offer a Flink binary that uses the Hadoop
jars provided by the user (=hadoop distribution)
