> 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
> Assignee: Martin Junghanns
> 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.
