-------------------------------------

             Summary: Configuration not visible in gui when job is running
                 Key: FLINK-3583
                 URL: https://issues.apache.org/jira/browse/FLINK-3583
             Project: Flink
          Issue Type: Bug
          Components: Web Client, Webfrontend
    Affects Versions: 1.0.0
            Reporter: Michał Fijołek
            Priority: Minor
             Fix For: 1.0.1


Hello.
I can see that configuration is not visible in frontend when job is running.

When I cancel job, configuration appears but `User configuration` is still not visible, although server sends `user-config`.

rest-call: http://localhost:8081/jobs/jobId/config returns
{code}
{
    "jid": "71e47c0772c7d62b81f7e3385d429cca",
    "name": "Flink Streaming Job",
    "execution-config": {
        "execution-mode": "PIPELINED",
        "restart-strategy": "Restart with fixed delay (5000 ms). #3 restart attempts.",
        "job-parallelism": 1,
        "object-reuse-mode": false,
        "user-config": {
            "jobmanager.web.log.path": "./data/dummyLogFile.txt",
            "local.start-webserver": "true"
        }
    }
}
{code}

So there are two problems:
_1. User cannot see configuration when job is running which is not really useful_
I can see that it happens because of
{code}
ExecutionConfig ec = graph.getExecutionConfig();
if (ec != null) { ... }
{code}
 in {{JobConfigHandler}}. Why {{executionConfig}} is marked as "// ------ Fields that are only relevant for archived execution graphs ------------" and can it be initialized earlier let's say in ExecutionGraph constructor?

_2. Even when configuration is visible, frontent probably parses it badly_
This should be simple to fix

I'm happy to implement both fixes if you don't mind
