I have a batch job with takes 2 parameters. when I pass these arguments while running the jar file directly, it works. Also when i pass these arguments via the shell of the spring cloud dataflow it works:
dataflow:>task launch --name adv-load --arguments "appnexus_seat=SEAT_MIQ_1 last_modified=2018/08/10"
Launched task 'adv-load'
But when I pass the similar arguments while running the task form the UI, it fails. Example, In the UI, i passed: appnexus_seat & last_modified as 2 keys with the same values as above but a different date so that it doesnt think its the same job. This failed.
I did however manage to find the issue. When i run the task via shell, in the logs I get this:
2018-09-21 14:04:50.970 INFO 4035 --- [ main] o.s.b.a.b.JobLauncherCommandLineRunner : Running default command line with: [appnexus_seat=SEAT_MIQ_1, last_modified=2018/08/10, --spring.cloud.task.executionid=5]

Whereas when i run it via the Ui i get this:

If you look at the difference you can see that when i run it via the shell it gives a space between the 2 arguments whereas when i run it via the Ui its doesn't. Not giving this space results in an issue as the value of the first argument becomes "SEAT_MIQ_1,last_modified=2018/08/10" instead of just being "SEAT_MIQ_1" and last_modified being another argument.
Please let me know how to resolve this. Thanks. :)
When you run the task from the UI, you need to specify each argument in a separate field:
This will correctly pass parameters to your task.
