I issued a PR yesterday (https://github.com/apache/flink/pull/1903) that should
fix this issue. Maybe it could worth to also add a {{closeOutputFormat()}} for
{{OutputFormat}} too?

> Add open and close methods to manage IF lifecycle

> Key: FLINK-3777
> URL: https://issues.apache.org/jira/browse/FLINK-3777
> Project: Flink
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.0.1
> Reporter: Flavio Pompermaier
> Assignee: Flavio Pompermaier
> Labels: inputformat, lifecycle
>
> At the moment the opening and closing of an inputFormat are not managed,
> although open() could be (improperly IMHO) simulated by configure().
> This limits the possibility to reuse expensive resources (like database
> connections) and manage their release.
> Probably the best option would be to add 2 methods (i.e. openInputformat()
> and closeInputFormat() ) to RichInputFormat*
> * NOTE: the best option from a "semantic" point of view would be to rename
> the current open() and close() to openSplit() and closeSplit() respectively
> while using open() and close() methods for the IF lifecycle management, but
> this would cause a backward compatibility issue...
