Subject [jira] [Commented] (FLINK-3554) Bounded sources should emit a Max Watermark when they are done
Date Tue, 01 Mar 2016 10:35:18 GMT

    [ https://issues.apache.org/jira/browse/FLINK-3554?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15173563#comment-15173563
] 

Stephan Ewen commented on FLINK-3554:
-------------------------------------

A good point to emit the {{Long.MAX_VALUE}} watermark is in the source operator, after the
{{run()}} function has properly exited (that only ever happens on bounded sources).

In addition, the operator must not be *stopped* or *canceled*.

before shutting down.
