Sample Spark-Submit Wrapper

This directory provides a simple wrapper library that can be used to submit a Spark Connect Go application to a Spark Cluster.

Wrapper Library

The wrapper library expects to variable input values:

The path to the binary file that contains the Spark Connect Go application. This path is specified via the Spark conf property spark.golang.binary.
The actual binary has to be submitted as part of the application using the --files parameter to the spark-submit script.

Building the libary can be done using:

sbt package

Run Script

The run.sh script is a simple script that can be used to submit a Spark Connect Go application to a Spark Cluster. The script can be called as follows:

export SPARK_HOME=/path/to/spark
./run.sh ../cmd/spark-connect-example-spark-session/spark-connect-example-spark-session

When this is called from the current directory and with the Spark Connect Golang client build, it will submit the example application to the Spark Cluster.

The run.sh script can be modified according to your needs.
