[jira] [Created] (FLINK-4624) Gelly's summarization algorithm cannot deal with null vertex group values

Till Rohrmann created FLINK-4624:
------------------------------------

             Summary: Gelly's summarization algorithm cannot deal with null vertex group values
                 Key: FLINK-4624
                 URL: https://issues.apache.org/jira/browse/FLINK-4624
             Project: Flink
          Issue Type: Bug
          Components: Gelly
            Reporter: Till Rohrmann
             Fix For: 1.2.0


Gelly's {{Summarization}} algorithm cannot handle null values in the `VertexGroupItem.f2`. This behaviour is hidden by using Strings as a vertex value in the {{SummarizationITCase}}, because the {{StringSerializer}} can handle null values.
