Flink版本 - 1.1.0

请你详细说明一下。我在进行以顶点为中心的图遍历时得到了这个。

顶点是Tuple2的DataSet 和edge是Tuple3的数据集

对于顶点和边缘，我可以使用collect打印值。

对于您来说可能为时已晚，但对于其他与flink 1.2有相同问题的人可能有所帮助，我刚刚找到了该线程，因为我遇到了相同的问题，并且您的意见对我有帮助

您似乎无法使用接口，TABLESPACE或compute(Vertex<String, VertexData> vertex, MessageIterator<Collection<MessageData>> messages)出现了相同的错误

但是它可以与compute(Vertex<String, VertexData> vertex, MessageIterator<List<MessageData>> messages)

一起使用
