[jira] [Created] (GIRAPH-752) Better support for supernodes

Maja Kabiljo created GIRAPH-752:
-----------------------------------

             Summary: Better support for supernodes
                 Key: GIRAPH-752
                 URL: https://issues.apache.org/jira/browse/GIRAPH-752
             Project: Giraph
          Issue Type: Bug
            Reporter: Maja Kabiljo
            Assignee: Maja Kabiljo


We've seen before that we crash when we have a vertex which receives a lot of messages and we don't use a combiner. That is because the total size of serialized messages for that vertex is bigger than the allowed size of an array. 
We should implement OutputStream which can handle arbitrary size of data and add an option to use that kind of stream for messages.
