RE: What is the use of ‘Run As Instance’ option in job flow and how it works?
Run as Instance is used to execute multiple Instances of a Job Flow in parallel.
Select a single Job Flow to execute from the list of Job Flows on canvas. On the Actions menu, click Run as Instance.
Provide the Instance Name, param file and parameter details to be used for this instance of the Job Flow
To view the execution status of the Job Flow instance in the Monitor module, open the Monitor module.
In Monitor, the Job Flow name is displayed as Instance name[Job Flow Name].
