I've created an environment where I've set up 3 Docker containers, 1 for Airflow using the puckel/docker-airflow image with spark and hadoop additionally installed. The other two containers are basically imitating spark master and worker (used gettyimages/spark Docker image to create this). All 3 containers are connected to each other via a bridge network, so all containers are able to communicate with each other.
What I'm trying to do next is to submit spark job from the Airflow container to the Spark cluster (master).
As an initial example, I'm using the wordcount sample script. I created a sample.txt file in the airflow container at path usr/local/airflow/sample.txt. I've bashed into the Airflow container and I'm using the command given below to run the wordcount.py on spark master located at the ip which I found after inspecting the bridge network.
spark-submit --master spark://ipaddress:7077 --files usr/local/airflow/sample.txt /opt/spark-2.4.1/examples/src/main/python/wordcount.py sample.txt
After submitting the script, from the logs, I can see that a connection has been established with the master (from airflow container), and it also copied the file specified by --files to the master and worker, but then it just errors out saying,
java.io.FileNotFoundException: File file:/usr/local/airflow/sample.txt does not exist
As per my understanding (could be wrong), but when we specify files to copy to master using --files you can access it directly via the file name (sample.txt in my case). So what I'm trying to figure out is if a job has been submitted and the file has been copied to master, then why is it searching in the location file:/usr/local/airflow/sample.txt? How do I make it refer to the correct path?
I apologize as this question has been asked a couple of times, but I've read all the related question on stackoverflow, but I'm still unable to resolve this. I'd really appreciate y'alls help on this.
Thanks.
