I wanted to install graphframes for spark following the instructions on the spark website, but the command:
pyspark --packages graphframes:graphframes:0.8.1-spark3.0-s_2.12
did not work for me.
I tried many ways to install, but decided to stay at downloading graphframes .jar, adding it to the general list of Spark .jar files and adding it manually in the code spark.sparkContext.addPyFile("path to /spark-2.4.7-bin-hadoop2.7/jars/graphframes-0.8.1-spark3.0-s_2.12.jar").
After that, the library is imported, but there is always an error when creating the GraphFrame. And I just have no idea how to solve it.
My
.bashrcvariables:
export CLASSPATH="/home/german/spark-2.4.7-bin-hadoop2.7/jars"
export HADOOP_CONF_DIR="/home/german/spark-2.4.7-bin-hadoop2.7/conf"
export HADOOP_HOME="/home/german/spark-2.4.7-bin-hadoop2.7"
export HADOOP_SECURITY_LOGGER=ERROR,console

My jdk version 1.8, python 3.7.10, OS: Ubuntu 20.04 LTS.
from pyspark.sql import SparkSession
spark = SparkSession.builder\
.config("spark.sql.warehouse.dir", "spark_warehouse")\
.getOrCreate()
spark.sparkContext.setCheckpointDir("graphframes_checkpoints")
spark.sparkContext.addPyFile("path to /spark-2.4.7-bin-hadoop2.7/jars/graphframes-0.8.1-spark3.0-s_2.12.jar")
vertices = spark.read.parquet("tmp_dfs/parquet/vertices.parquet")
edges = spark.read.parquet("tmp_dfs/parquet/edges.parquet")
from graphframes import *
graph = GraphFrame(vertices, edges)
And I get the error:

I may have chosen the wrong installation method or something else. I would be glad to hear any suggestions on how to solve this problem.
