    [ https://issues.apache.org/jira/browse/FLINK-2357?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14802919#comment-14802919

ASF GitHub Bot commented on FLINK-2357:

Github user aljoscha commented on the pull request:

    For a streaming job, when I open the running job overview the plan is displayed correctly.
When I then switch over to another tab and return to the plan view all the operators are disconnected
and shown one above the other.

> We need to improve rework the Job Manager Web Frontend.
> The current web frontend is limited and has a lot of design issues
>   - It does not display and progress while operators are running. This is especially
problematic for streaming jobs
>   - It has no graph representation of the data flows
>   - it does not allow to look into execution attempts
>   - it has no hook to deal with the upcoming live accumulators
>   - The architecture is not very modular/extensible
> I propose to add a new JobManager web frontend:
>   - Based on Netty HTTP (very lightweight)
>   - Using rest-style URLs for jobs and vertices
>   - integrating the D3 graph renderer of the previews with the runtime monitor
>   - with details on execution attempts
>   - first class visualization of records processed and bytes processed
