[jira] [Created] (FLINK-21469) stop-with-savepoint --drain doesn't advance watermark for sources chained to MultipleInputStreamTask

Piotr Nowojski created FLINK-21469:
--------------------------------------

             Summary: stop-with-savepoint --drain doesn't advance watermark for sources chained to MultipleInputStreamTask
                 Key: FLINK-21469
                 URL: https://issues.apache.org/jira/browse/FLINK-21469
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Task
    Affects Versions: 1.12.1, 1.13.0
            Reporter: Piotr Nowojski


{{StreamTask#advanceToEndOfEventTime()}} is used to bump the watermark to {{MAX_WATERMARK}}. However this method is only implemented for the source tasks (legacy and FLIP-27). Because of that watermarks are not advanced to end of time if job has sources chained to {{MultipleInputStreamTask}}.
