------------------------------------

             Summary: Flink fails due to non-initialized RuntimeContext in CombiningUnilateralSortMerger
                 Key: FLINK-1574
                 URL: https://issues.apache.org/jira/browse/FLINK-1574
             Project: Flink
          Issue Type: Bug
          Components: Local Runtime
    Affects Versions: 0.9
            Reporter: Fabian Hueske
            Priority: Critical
             Fix For: 0.9


The {{AggregatingUdf}} combiner cannot be opened in a {{CombiningUnilateralSortMerger }} because its {{RuntimeContext}} is {{null}}.
The problem is that the runtime context of the {{RegularPactTask}} is set after the local strategies are initialized.

I have a fix for that.
