Is it possible to run long running task without killing it, I did try async fire-forget but it still requires to enter time?

Or let me ask it this way, How do i run a java app on machines, for which i might need to change parameters when i start it off.

basically kickoff a java process (jar) with some parameters, if i wish to change it, kill the java process running and restart with new parameters. This is for our dev environment.

I would either make an init script, or just use nohup and record/find the pod to stop it when restarting.

I actually did try command/shell both with nohup

action: shell nohup /usr/bin/java -jar kk.jar arg1 arg2 &  
action: command nohup /usr/bin/java -jar kk.jar arg1 arg2 &

It still does not seem to go to the next task, Only when i kill java on remote machine does it proceed,

Just set the time to some very high value, like a day or two.

If you want to do something that runs forever, it seems you should  
write a service init script.

Thank you very much, for now I will just set it as a Day and also look at writing an init script and also reading a config file, As i need to change parameters.

One last question in this thread, When i run a playbook in async mode, I do not get the job id, But i can go on the remote node and find it. Is there a way i can kill the jobs by jobid, I did try async\_status mode cleanup, But that does not kill the long running task,

Thanks for the help!!
