+1 for the either type solution :-)

Hi all,
thanks for reporting the issue! I just looked into it. The
VertexGroupReduce outputs two semantically different tuples: one for
each vertex without the value (null) and one tuple representing the
whole group including the value. As Till pointed out, this crashes if
the value has no se
Hi,
thanks for looking into this Till! I'm not quite sure what the algorithm
behavior should be when the vertex value is null (probably skip the
record?). Let's wait for Martin's input.
Cheers,

Hi Till,
Thanks a lot for your help! I'll try to use another variable type in the
meantime.
Best regards,

Hi Olga,
it’s indeed an error in Flink’s Summarization algorithm. The problem is the
following: The vertex group value of the VertexGroupItem is null in the
VertexGroupReducer. This works in the SummarizationIT case because the
vertex value is of type String and the StringSerializer can deal with
Hi Till,
I've created a simple (Java) example to show you what's going on. The code
is in attachment and shown below. This example creates simple graph with
Double EV and Long VV. Then it runs Summarization, that should compute a
condensed version of the input graph by grouping vertices and edges
Hi Olga,
can you provide us with a little bit more details about the problem. The
full stack trace of the exception and the program you're trying to run
would be helpful.
Cheers,
Till

Hi devs,
Do you know if there is an example (besides ITCase) of usage of
Summarization Library in Gelly? I'm having some problems trying to use it
in my code. Particularly, I cannot print output edges ( it throws the
following exception: Exception in thread "main"
org.apache.flink.runtime.client.J
