我使用spark 2.4.4运行一个简单的emr群集，我想使用graphframes v0.7运行以下代码：

from pyspark import *
from pyspark.sql import *
from graphframes import *

sc= SparkContext().getOrCreate()
sc.setLogLevel("ERROR")
spark = SparkSession.builder.appName('graphFrames').getOrCreate()
spark.sparkContext.addPyFile("/home/hadoop/jars/graphframes.zip")

vertices = spark.createDataFrame([('1', 'Carter', 'Derrick', 50),
                                  ('2', 'May', 'Derrick', 26),
                                 ('3', 'Mills', 'Jeff', 80),
                                  ('4', 'Hood', 'Robert', 65),
                                  ('5', 'Banks', 'Mike', 93),
                                 ('98', 'Berg', 'Tim', 28),
                                 ('99', 'Page', 'Allan', 16)],
                                 ['id', 'name', 'firstname', 'age'])
edges = spark.createDataFrame([('1', '2', 'friend'),
                               ('2', '1', 'friend'),
                              ('3', '1', 'friend'),
                              ('1', '3', 'friend'),
                               ('2', '3', 'follows'),
                               ('3', '4', 'friend'),
                               ('4', '3', 'friend'),
                               ('5', '3', 'friend'),
                               ('3', '5', 'friend'),
                               ('4', '5', 'follows'),
                              ('98', '99', 'friend'),
                              ('99', '98', 'friend')],
                              ['src', 'dst', 'type'])
g = GraphFrame(vertices, edges)

## Take a look at the DataFrames

g.vertices.show()
g.edges.show()

## Check the number of edges of each vertex

g.degrees.show()

它被发现并导入如下：

当我运行一个简单的graphframe示例时，遇到以下错误：

    g = GraphFrame(vertices, edges)

在spark-default.sh中还添加了jar包：

spark.jars.packages              graphframes:graphframes:0.7.0-spark2.4-s_2.11

还尝试了hughcristensen建议的步骤，如下所示：https://github.com/graphframes/graphframes/issues/172
我真的很感激任何帮助，因为我不知道我还能做什么。
