This should also be an AsyncExceptionChecker, same for the parameter. For
the time handling, this can get a `TimeServiceProvider`, that way, things are
cleanly separated.
> Fix Streaming File Source Timestamps/Watermarks Handling
> --------------------------------------------------------
>
> Key: FLINK-4329
> URL: https://issues.apache.org/jira/browse/FLINK-4329
> Project: Flink
> Issue Type: Bug
> Components: Streaming Connectors
> Affects Versions: 1.1.0
> Reporter: Aljoscha Krettek
> Assignee: Kostas Kloudas
> Fix For: 1.1.1
>
>
> The {{ContinuousFileReaderOperator}} does not correctly deal with watermarks,
> i.e. they are just passed through. This means that when the
> {{ContinuousFileMonitoringFunction}} closes and emits a {{Long.MAX_VALUE}}
> that watermark can "overtake" the records that are to be emitted in the
> {{ContinuousFileReaderOperator}}. Together with the new "allowed lateness"
> setting in window operator this can lead to elements being dropped as late.
> Also, {{ContinuousFileReaderOperator}} does not correctly assign ingestion
> timestamps since it is not technically a source but looks like one to the
> user.
