>
> Key: SPARK-39813
> URL: https://issues.apache.org/jira/browse/SPARK-39813
> Project: Spark
> Issue Type: Bug
> Components: PySpark
> Affects Versions: 3.3.0
> Environment: I am running this in a docker built from the jupyter/all-spark-notebook image.
> Reporter: David Lassiter
> Priority: Major
> Labels: AWS
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> My team has a bash script + python script that uses pyspark to extract data from a hive database. The scripts work when run on a server. However, we need to containerize this since we will not have access to that server in the future.
> Thus, I am trying to get the job to work from a container.
> When trying to run the scripts locally or in a docker container, I am running into driver issues. Unfortunately, nobody on my team helped set up the environment on the server, where everything is working. Thus, we are having a hard time figuring out what is wrong with our local/containerized environments and cannot replicate a successful script run.
>
> From a container, I run a bash script that does the following:
>
> ```\{bash}
> $SPARK_HOME/bin/spark-submit etl_job.py
> ```
>
> The contents of `etl_job.py` are as follows:
> ```\{python}
> print('\n\nStarting python job\n\n')
> from pyspark.context import SparkContext
> from pyspark.sql.session import SparkSession
> from credentials import PRESTO_USER, PRESTO_PASSWORD, PRESTO_URL, PRESTO_SSL, SSL_PASSWORD, TEST_SCHEMA, TEST_TABLE
> import pandas as pd
> print('\n\nStarting spark session \n\n')
> sc = SparkContext.getOrCreate()
> spark = SparkSession(sc)
> print('\n\nConnecting to Presto\n\n')
> Prestoprod = (
> spark.read.format("jdbc")
> .option("url", PRESTO_URL)
> .option("user", PRESTO_USER)
> .option("password", PRESTO_PASSWORD)
> .option("driver", "com.facebook.presto.jdbc.PrestoDriver")
> .option("SSL", "true")
> .option("SSLKeyStorePath", PRESTO_SSL)
> .option("SSLKeyStorePassword", SSL_PASSWORD)
> )
>
> print('\n\nTrying to query Presto.\n\n')
> query = "select * from hive.{}.{}".format(TEST_SCHEMA, TEST_TABLE)
> results = (
> Prestoprod.option(
> "query",
> query
> )
> .load()
> )
> ```
>
> However, when I run the job, I get the following error:
> ```
> py4j.protocol.Py4JJavaError: An error occurred while calling o33.load.
> : java.lang.ClassNotFoundException: com.facebook.presto.jdbc.PrestoDriver
> ```
>
> Here is the full log:
> ```
