I'm trying to run a simple Graphframes example. I have both Python 3.6.8 and Python 2.7.15, as well as Apache Maven 3.6.0, Java 1.8.0, Apache Spark 2.4.4 and Scala code runner version 2.11.12.
I got this error:
An error occurred while calling o58.loadClass.
: java.lang.ClassNotFoundException: org.graphframes.GraphFramePythonAPI
I tried to put this solution in motion, but I became stuck on step 2.
I ran pyspark --packages graphframes:graphframes:0.7.0-spark2.4-s_2.11 and got the following output:
Python 2.7.15+ (default, Jul 9 2019, 16:51:35)
[GCC 7.4.0] on linux2

Needless to say this is not the expected output, all of the links that timed out lead to 404s. My PC is behind a proxy, but the proxy settings are configured in the Maven settings files and I know that they work correctly.
Are there other proxy settings to change? Is there maybe another way to install these dependencies?
EDIT
I changed my /usr/share/jupyter/kernels/python3/kernel.json file to:
{
"argv": [
"/usr/bin/python3",
"-m",
"ipykernel_launcher",
"-f",
"{connection_file}"
],
"env": {
"PYSPARK_SUBMIT_ARGS": "--packages graphframes:graphframes:0.7.0-spark2.4-s_2.11 --master local[10] pyspark-shell"
},
"display_name": "Python 3",
"language": "python"
}
then tried to run my Python script in a Jupyter Notebook. This did not work. In fact now it causes this error as soon as I run my Python script (after it has imported the required imports, it crashes)
EDIT 2
I tweaked my Firefox and downloaded the files myself.
-rw-rw-r-- 1 jessica jessica 381110 Oct 22 12:17 graphframes-0.7.0-spark2.4-s_2.11.jar
-rw-rw-r-- 1 jessica jessica 2541 Oct 22 12:14 graphframes-0.7.0-spark2.4-s_2.11.pom
I then ran mvn install:install-file -Dfile=graphframes-0.7.0-spark2.4-s_2.11.jar -DpomFile=graphframes-0.7.0-spark2.4-s_2.11.pom, and though that procedure was successful, I still can't run my script (still for the same reason). However, there is now a graphframes folder in my maven repository that contains all the required files.
EDIT 3
I have uninstalled and reinstalled Jupyter, notebook, graphframes, toree, iPython and have added Anaconda - all for both Python 2.7 and Python 3. I could not install the Apache Toree kernel (v0.3.0) for Python/Pyspark (I do have SQL and Scala, apparently the Python/Pyspark kernel it is no longer supported - solutions for this are also welcomed).
My SPARK_HOME=~/spark/spark-2.2.0-bin-hadoop2.7 variable has also been set, as well as PYSPARK_DRIVER_PYTHON="jupyter" and PYSPARK_DRIVER_PYTHON_OPTS="notebook".
I solved the issue, using advice from this site.
Long story short, put the jars straight in $SPARK_HOME/jars
