Martin Junghanns commented on FLINK-4624: ----------------------------------------- No, I wanted to have an {{Either<NullValue, VV>}} as field type in a tuple. I guess, I will go ahead with the first proposed method and forward the value for all tuples. > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
