Good point. I'll fix those tests...
> Make flink-core independent of Hadoop

> Key: FLINK-4316
> URL: https://issues.apache.org/jira/browse/FLINK-4316
> Project: Flink
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.1.0
> Reporter: Stephan Ewen
> Assignee: Stephan Ewen
> Fix For: 1.2.0
>
>
> We want to gradually reduce the hard and heavy mandatory dependencies in
> Hadoop. Hadoop will still be part of (most) flink downloads, but the API
> projects should not have a hard dependency on Hadoop.
> I suggest to start with {{flink-core}}, because it only depends on Hadoop for
> the {{Writable}} type, to support seamless operation of Hadoop types.
> I propose to move all {{WritableTypeInfo}}-related classes to the
> {{flink-hadoop-compatibility}} project and access them via reflection in the
> {{TypeExtractor}}.
> That way, {{Writable}} types will be out of the box supported if users have
> the {{flink-hadoop-compatibility}} project in the classpath.
