Let this test base extend the `TestLogger` for better logging output on
Travis.
> Add outer joins to API, Optimizer, and Runtime
> ----------------------------------------------
>
> Key: FLINK-2106
> URL: https://issues.apache.org/jira/browse/FLINK-2106
> Project: Flink
> Issue Type: Sub-task
> Components: Java API, Local Runtime, Optimizer, Scala API
> Reporter: Fabian Hueske
> Assignee: Ricky Pogalz
> Priority: Minor
> Fix For: pre-apache
>
>
> Add left/right/full outer join methods to the DataSet APIs (Java, Scala), to
> the optimizer, and the runtime of Flink.
> Initially, the execution strategy should be a sort-merge outer join
> (FLINK-2105) but can later be extended to hash joins for left/right outer
> joins.
