------------------------------------

             Summary: Use DataSet's count() and collect() to simplify Gelly methods
                 Key: FLINK-1632
                 URL: https://issues.apache.org/jira/browse/FLINK-1632
             Project: Flink
          Issue Type: Improvement
          Components: Gelly
    Affects Versions: 0.9
            Reporter: Vasia Kalavri


The recently introduced count() and collect() methods of DataSet can be used to simplify several Gelly methods. We can get rid of GraphUtils and also simplify methods which return DataSets with single values, such as numberOfVertices() and isWeaklyConnected().
