Till Rohrmann commented on FLINK-20115:
---------------------------------------
I continued testing and I noticed that when running a Flink job using the new
{{FileSource}} from the IDE (meaning the IDE spawns a JVM to run the job), it
won't properly terminate. I am a bit clueless why this is the case but somehow
the new {{FileSource}} must do something which the JVM termination does not
like. See FLINK-20266 for the respective ticket.
> Test Batch execution for the DataStream API
> --------------------------------------------
>
> Key: FLINK-20115
> URL: https://issues.apache.org/jira/browse/FLINK-20115
> Project: Flink
> Issue Type: Sub-task
> Components: API / DataStream
> Affects Versions: 1.12.0
> Reporter: Robert Metzger
> Assignee: Till Rohrmann
> Priority: Critical
> Fix For: 1.12.0
>
>
> Test the following new features:
> - https://issues.apache.org/jira/browse/FLINK-19316
> - https://issues.apache.org/jira/browse/FLINK-19268
> - https://issues.apache.org/jira/browse/FLINK-19758
> The three issues can really only be tested in combination. FLINK-19316 is
> done but missing documentation.
> Write an example that uses a (new) FileSource, a (new) FileSink, some random
> transformations
> Run the example in BATCH mode
> How ergonomic is the API/configuration?
> Are there any weird log messages/exceptions in the JM/TM logs
> Maybe try sth that doesn't work on BATCH execution, such as
> iterations/feedback edges.
> ----
> [General Information about the Flink 1.12 release
> testing|https://cwiki.apache.org/confluence/display/FLINK/1.12+Release+-+Community+Testing]
> When testing a feature, consider the following aspects:
> - Is the documentation easy to understand
> - Are the error messages, log messages, APIs etc. easy to understand
> - Is the feature working as expected under normal conditions
> - Is the feature working / failing as expected with invalid input, induced
> errors etc.
> If you find a problem during testing, please file a ticket
> (Priority=Critical; Fix Version = 1.12.0), and link it in this testing ticket.
> During the testing, and once you are finished, please write a short summary
> of all things you have tested.
