Unfortunately, this means that users now have to manually specify a
`TypeInformation` that they can get from
`TypeExtractor.createHadoopWritableTypeInfo(MyWritable.class)`.
I'm not sure how often people are using Hadoop Writables in their Scala
code but this is definitely something that will break.
> Provide Flink binary release without Hadoop

> Issue Type: Improvement
> Components: Build System
> Reporter: Robert Metzger
> Assignee: Aljoscha Krettek
>
> 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)
