Cory Maklin created SPARK-34870:
-----------------------------------
Summary: Jars downloaded with the --packages argument are not
added to the classpath for executors.
Key: SPARK-34870
URL: https://issues.apache.org/jira/browse/SPARK-34870
Project: Spark
Issue Type: Bug
Components: Spark Submit
Affects Versions: 3.0.0
Environment: Spark worker running inside a Kubernetes pod with a
Bitnami Spark image, and the driver running inside of a Jupyter Spark
Kubernetes pod.
Reporter: Cory Maklin
When Spark is run in local mode, it works as expected. However, when Spark is
run in client mode, it copies the jars to the executor ($SPARK_HOME/work/<app
id>/<executor id>), but never adds them to the classpath.
It might be worth noting that `spark.jars` does add the jars to the classpath,
but unlike `spark.jars.packages` it doesn't automatically download the jar's
compiled dependencies.
```
spark = SparkSession.builder\
.master(SPARK_MASTER)\
.appName(APP_NAME)\
...
.config("spark.jars.packages", DEPENDENCY_PACKAGES) \
...
.getOrCreate()
```
