Subject Re: Passing Custom App Id for consumption in History Server
Date Sun, 04 Sep 2016 01:36:53 GMT
How about this:

1. You create a primary key in your custom system.
2. Schedule the job with custom primary name as the job name.
3. After setting up spark context (inside the job) get the application id.
Then save the mapping of App Name & AppId from spark job to your custom
database, through some web service.
