Spark cluster information:
- Spark version: 2.2.0
- Cluster contains a master node with 2 worker nodes
- Cluster Manager Type: standalone
I submit a jar to spark cluster from one of the workers and I want to receive the driver-Id from the submission so that I can use that id for later application status checking. The problem is that I am not getting any output in the console. I use port 6066 for submission and set deploy mode to cluster.
By running
spark-submit --deploy-mode cluster --supervise --class "path/to/class" --master "spark://spark-master-headless:6066" path/to/app.jar
in the spark log file I am able to see the json response of the submission below, which is the exact thing that I want:

But I want to have this information in the console so that I can direct it to a separate file than the spark logs. I assume that some messages should be get printed when the above command gets run. I even used --verbose mode in the command so that maybe that helps but still the output in the console is empty.
The only thing that gets printed to console is
Running Spark using the REST application submission protocol. While in this page's question section, the user is able to see more than this.
I even tried to change the Logger level in my application code but that also didn't help. (based on some ideas from here)
Then the question would be, how come that I am not getting any output in the console and what can I do to get the info that I want to get printed to console? P.S. I have developed and tweaked the cluster and the jar file to a good amount that maybe I have something somewhere causing the output not to get printed. What are the possible places I can check to fix this.
Update:
I found out that the default log4j.properties of spark has been edited. Here is the content:
# Set everything to be logged to the console
log4j.rootCategory=INFO, RollingAppender
log4j.appender.console=org.apache.log4j.ConsoleAppender

I assume that this is not letting the verbose command to work. How can I change this to have get some content with --verbose?
