Ok. I'll rebase the change and fix merge conflicts.
> Enhance Dashboard to show Execution Attempts
> --------------------------------------------
>
> Key: FLINK-3030
> URL: https://issues.apache.org/jira/browse/FLINK-3030
> Project: Flink
> Issue Type: Improvement
> Components: Webfrontend
> Affects Versions: 0.10.0
> Reporter: Stephan Ewen
> Assignee: Ivan Mushketyk
> Fix For: 1.0.0
>
>
> Currently, the web dashboard shows only the latest execution attempt. We
> should make all execution attempts and their accumulators available for
> inspection.
> The REST monitoring API supports this, so it should be a change only to the
> frontend part.
