Description

When we submit Flink template task to the Yarn cluster through Dolphin, we want task name to be displayed in the Yarn Web UI as yarn application name.
Now we configure -Dyarn.application.name=WF_${job_name} in the Flink option parameter, and the job_name parameter is passed to start the workflow.

Use case

we hope flink submit option parameter supports placeholder substitution.
