Ok, thanks for the clarification on yarn session. 

 I am trying to connect to job manager on 8081 but it's not connecting. 

So this is the address shown on my Flink job UI and i am trying to connect rest address on 8081 but its refusing connection.

Hi Anuj,

Afaik, the REST API should work for both modes. What is the issue? Maybe, some network problem to connect to YARN application master?

Best,
Andrey

I am running some stream jobs that are long-running always. I am currently submitting each job as a standalone job on yarn. 

1. I need to understand what is the advantage of using yarn-session and when should I use that. 

2. Also, I am not able to access rest API services is it because I am running as standalone job over yarn. Is REST API works only in yarn-session?
