--------------------------------------
Summary: Stop and remove driver from supervised mode in
spark-master interface
Key: SPARK-9008
URL: https://issues.apache.org/jira/browse/SPARK-9008
Project: Spark
Issue Type: New Feature
Reporter: Jesper Lundgren
The cluster will automatically restart failing drivers when launched in
supervised cluster mode. However there is no official way for a operation team
to stop and remove a driver from restarting in case it is malfunctioning.
I know there is "bin/spark-class org.apache.spark.deploy.Client kill" but this
is undocumented and does not always work so well.
It would be great if there was a way to remove supervised mode to allow kill -9
to work on a driver program.
The documentation surrounding this could also see some improvements. It would
be nice to have some best practice examples on how to work with supervised
mode, how to manage graceful shutdown and catch TERM signals. (TERM signal will
end with wrong exit code and trigger restart when using supervised mode unless
you change the exit code in the application logic)
