Needed to add --conf spark.driver.extraClassPath=

[satindern]

The Documentation says to install for example the cudf-0.15-SNAPSHOT-cuda10-1.jar and rapids-4-spark_2.12-0.1.0.jar into the /opt/sparkRapidsPlugin directory.
Then export

export SPARK_RAPIDS_DIR=/opt/sparkRapidsPlugin
export SPARK_CUDF_JAR=${SPARK_RAPIDS_DIR}/cudf-0.15-SNAPSHOT-cuda10-1.jar
export SPARK_RAPIDS_PLUGIN_JAR=${SPARK_RAPIDS_DIR}/rapids-4-spark_2.12-0.2.0-SNAPSHOT.jar

Under https://github.com/NVIDIA/spark-rapids/blob/branch-0.2/docs/getting-started.md#spark-gpu-scheduling-overview, you discuss the need to specify --conf spark.executor.resource.gpu.discoveryScript=./getGpusResources.sh

however I also needed to include --conf spark.driver.extraClassPath=${SPARK_CUDF_JAR}:${SPARK_RAPIDS_PLUGIN_JAR}

so there are cluster manager specific sections and unfortunately need slightly different configs for them. I'm assuming you are running in standalone mode? Were you running interactive mode (spark-shell or pyspark) or spark-submit in cluster mode?

What error did you get without specifying that? You definitely need the spark.executor.extraClassPath but didn't think you needed the driver one but perhaps something has changed there.

Yes this was in standalone mode. I no longer have the error.
I either had to copy/move cudf-0.15-SNAPSHOT-cuda10-1.jar and rapids-4-spark_2.12-0.1.0.jar into /opt/spark/spark-3.0.1-SNAPSHOT-bin-hadoop3/jars or use the additional --conf spark.driver.extraClassPath=${SPARK_CUDF_JAR}:${SPARK_RAPIDS_PLUGIN_JAR}

ok thanks, we should reproduce and investigate

I was testing 0.1 release with standalone mode and I also had to specify the driver extra classpath to get this to work. The issue is the plugin we are trying to load.
