Subject [jira] [Commented] (FLINK-2026) Error message in count() only jobs
Date Tue, 19 May 2015 08:14:59 GMT

    [ https://issues.apache.org/jira/browse/FLINK-2026?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14550017#comment-14550017

Sebastian Schelter commented on FLINK-2026:
-------------------------------------------

Wouldn't it be best to simply ignore the call to execute() if there is no more work to do?
I as user don't want to think about all the internals to be honest. For me its common to do
add a env.execute() call at the end of my flink code. Always having to remove that if I use
a count or print call somewhere seems tedious.

> If I run a job that only calls count() on a dataset (which is a valid data flow IMHO),
Flink executes the job but complains that no sinks are defined.
