-----------------------------------
Summary: NullPointerException while translating union node
Key: FLINK-996
URL: https://issues.apache.org/jira/browse/FLINK-996
Project: Flink
Issue Type: Bug
Reporter: Till Rohrmann
Assignee: Till Rohrmann
The NepheleJobGraphGenerator throws a NullPointerException when translating a
binary union operator. The BinaryUnionPlanNode is not replaced by a
NAryUnionPlanNode and thus is still treated as a DualInputVertex. Accessing the
driver code of the BinaryUnionPlanNode causes then the NullPointerException.
