Aljoscha Krettek commented on FLINK-20115:
------------------------------------------
Thanks for the thorough testing! Some of the stuff is already known (for
example FLINK-20098), I'm sorry you had to rediscover that again.
Regarding configuration and {{flink-conf.yaml}}: It's not a setting of the
cluster but still only of every job that happens to be started with that
{{flink-conf.yaml}}. But yes, I understand the concern. This is a side effect
of the fact that everything is configurable at all levels, including for
example the parallelism, which is also more a per-job thing but was always
configurable from the {{flink-conf.yaml}}.
We're not advocating that users should configure some things (including the
runtime mode) in the flink-conf.yaml, even though they theoretically could. And
I don't think that we should change this now because I think the fact that
everything is uniformly configurable has already been a benefit for users.

> 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.
