@tillrohrmann I've updated the PR. The changes to the EG we're reduced to a
minimum; `ExecutionGraph#fail()/suspend()` now take an `ErrorInfo` instead of a
`Throwable`. The old methods were kept to not require further changes in the EG.
In the EG `String getFailureCauseAsString()` was replaced with `ErrorInfo
getFailureCause()`. This is basically future-proofing; for FLINK-6042 i would
like to store additional meta data (task name/location) in the error info but
not add methods to the EG for each of them. This requires ErrorInfo to
implement Serializable.

> Project: Flink
> Issue Type: Improvement
> Components: Webfrontend
> Affects Versions: 1.3.0
> Reporter: Till Rohrmann
> Assignee: Chesnay Schepler
> Priority: Minor
>
> In order to better understand the behaviour of Flink jobs, it would be nice
> to add timestamp information to exception causing the job to restart or to
> fail. This information could then be displayed in the web UI making it easier
> for the user to understand what happened when.
