How to deploy Spark application jar file to Kubernetes cluster?
Ensure your.jar file is present inside the container image.
Instruction tells that it should be there:
Finally, notice that in the above example we specify a jar with aspecific URI with a scheme of local://. This URI is the location ofthe example jar that is already in the Docker image.
In other words, local:// scheme is removed from local:///examples/jars/spark-examples_2.11-2.3.0.jar and the path /examples/jars/spark-examples_2.11-2.3.0.jar is expected to be available in a container image.
Please make sure this absolute path /examples/jars/spark-examples_2.11-2.3.0.jar is exists.
Or you are trying loading a jar file in current directory, In this case it should be an relative path like local://./examples/jars/spark-examples_2.11-2.3.0.jar.
I'm not sure if spark-submit accepts relative path or not.
