Run Spark Rapids

This page helps you run Spark jobs on GPUs using the NVIDIA RAPIDS Accelerator by outlining setup steps, configuration, and verification procedures.

Prerequisites

• Ensure you have access to a cluster with GPU nodes and required permissions.
• Java, Hadoop, Spark, and Hive are already installed and accessible in your environment.
• CUDA libraries compatible with your RAPIDS version are installed.

Steps to Run Spark Rapids

1. Download the required JAR files.

wget http://repo1.acceldata.dev/repository/odp-central/com/nvidia/rapids-4-spark_2.12/25.06.0.3.3.6.2-1/rapids-4-spark_2.12-25.06.0.3.3.6.2-1-cuda11.jar

​

wget https://repo1.maven.org/maven2/ai/rapids/cudf/25.06.0/cudf-25.06.0-cuda11.jar

2. Set environment variables.

export HIVE_HOME=/usr/odp/3.3.6.2-1/hive

export SPARK_HOME=/usr/odp/3.3.6.2-1/spark3

export HADOOP_CLASSPATH=$(hadoop classpath)

3. Validate the CUDA validation.

Before running your Spark job, check CUDA availability:

nvidia-smi

This command shows the available GPUs and the current CUDA version.

4. Launch Spark-Shell with rapids.

$SPARK_HOME/bin/spark-shell \

  --master yarn \

  --conf spark.yarn.queue=GPU \

  --conf spark.plugins=com.nvidia.spark.SQLPlugin \

  --conf spark.rapids.sql.enabled=true \

  --conf spark.executor.resource.gpu.amount=1 \

  --conf spark.task.resource.gpu.amount=0.1 \

  --conf spark.resources.discoveryScript=$SPARK_HOME/examples/src/main/scripts/getGpusResources.sh \

  --conf spark.executor.resource.gpu.discoveryScript=$SPARK_HOME/examples/src/main/scripts/getGpusResources.sh \

  --conf spark.metrics.enabled=false \

  --jars rapids-4-spark_2.12-25.06.0.3.3.6.2-1-cuda11.jar,cudf-25.06.0-cuda11.jar

5. Run a sample job.

In the Spark shell, try running a basic DataFrame operation to test GPU acceleration:

val df = spark.range(1, 1_000_000)

df.selectExpr("id", "id * 2 as double_id").show()

or

val df = spark.range(1, 100000000).toDF("id")

val result = df.groupByExpr("id % 100").count()

result.show()

Monitor the Spark UI (typically at port 4040) to verify that GPU resources are being allocated and used for the tasks.

6. Validation the job execution.

• Check Spark logs in the Resource Manager for any RAPIDS library loading or GPU assignment errors.
• Confirm RAPIDS acceleration is being used with log entries about com.nvidia.spark.rapids.
• You can also set additional debug logs for more visibility:

--conf spark.rapids.sql.logging.enabled=true

Optional Steps

• Tuning: Adjust spark.executor.memory, spark.executor.cores, and spark.executor.instances for optimal performance.
• Library Version Check: Make sure Spark, CUDA, and CUDF versions are compatible.
• Python Jobs: If running with PySpark, update the above procedure accordingly (e.g., use pyspark instead of spark-shell).
