             Summary: Streaming File Source Must Correctly Handle 
Timestamps/Watermarks
                 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
             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.
