Why is this called `testForEmptyLocation`? Wouldn't
`testInputFormatLifeCycle` be a better name?
> FileSourceFunction not adjusted to new IF lifecycle
> ---------------------------------------------------
>
> Key: FLINK-4024
> URL: https://issues.apache.org/jira/browse/FLINK-4024
> Project: Flink
> Issue Type: Bug
> Components: Streaming
> Affects Versions: 1.1.0
> Reporter: Chesnay Schepler
> Assignee: Kostas Kloudas
> Priority: Critical
> Fix For: 1.1.0
>
>
> The InputFormat lifecycle was extended in
> ac2137cfa5e63bd4f53a4b7669dc591ab210093f, adding additional
> open-/closeInputFormat() methods.
> The streaming FileSourceFunction was not adjusted for this change, and thus
> will fail for every InputFormat that leverages these new methods.
