graphX​​不能绘制多重边线和顶点？ [英] graphX cannot graph multiple Edges and Vertices?

问题描述

我的顶点的类型是：

org.apache.spark.rdd.RDD [（（长，字符串），（长，字符串），（长，字符串））]

我的缘的类型是：

<$c$c>org.apache.spark.rdd.RDD[(org.apache.spark.graphx.Edge[String],org.apache.spark.graphx.Edge[String])]

当我试图图（顶点，边）。

When I tried to Graph(vertices, edges).

它说：

<console>:47: error: type mismatch;
 found   : org.apache.spark.rdd.RDD[((Long, String), (Long, String), (Long, String))]
 required: org.apache.spark.rdd.RDD[(org.apache.spark.graphx.VertexId, ?)]

<console>:47: error: type mismatch;
 found   : org.apache.spark.rdd.RDD[(org.apache.spark.graphx.Edge[String], org.apache.spark.graphx.Edge[String])]
 required: org.apache.spark.rdd.RDD[org.apache.spark.graphx.Edge[?]]

（长字符串）是tuple2。

(Long String) is tuple2.

推荐答案

我认为你必须既纠正你的顶点和边RDD。

I think you have to correct both your vertex and edge rdd.

顶点RDD它是一个RDD [（VertexId，vertexValueType）]

vertex rdd it is a rdd[(VertexId, vertexValueType)]

所以你要你的顶点RDD更改为：

so you have to change your vertex rdd to:

org.apache.spark.rdd.RDD[(VertexId, ((Long, String), (Long, String), (Long, String)))]

和边缘RDD它是一个RDD [边缘[edgeValueType]
所以实际上它应该是这样的：

and edge rdd it is a rdd[Edge[edgeValueType]] so indeed it should be like this:

org.apache.spark.rdd.RDD[org.apache.spark.graphx.Edge[String]]

也许你可以张贴code，你实际上是创造这个RDDS？

Maybe you can post a code where you actually create this rdds?
