Stephan Ewen resolved FLINK-402.
--------------------------------
Resolution: Won't Fix
Since the old java API is running out, the context checker becomes redundant.
> ContextChecker should give meaningful error messages
> ----------------------------------------------------
>
> Key: FLINK-402
> URL: https://issues.apache.org/jira/browse/FLINK-402
> Project: Flink
> Issue Type: Improvement
> Reporter: GitHub Import
> Priority: Trivial
> Labels: github-import
> Fix For: pre-apache
>
>
> Prior to optimization, Stratosphere checks that a `Plan` is properly wired
> (no loose ends, missing data sources, data sinks, etc.). This is done by the
> so-called `ContextChecker`.
> In ([#401|https://github.com/stratosphere/stratosphere/issues/401] |
> [FLINK-401|https://issues.apache.org/jira/browse/FLINK-401]) the
> `ContextChecker`, correctly found a problem with a plan but returned a
> confusing `IndexOutOfBoundsException`.
> The `ContextChecker` should return error messages that are meaningful for the
> user.
> Also, I don't think `ContextChecker` is good name for this component.
> Something like `PlanChecker` would be more meaningful and tell the user that
> there might be a problem with the plan.
