[VOTE] Apache Flink Release 1.9.0, release candidate #2

[Jark Wu-2]

Hi Bowen,

Thanks for reporting this.
However, I don't think this is an issue. IMO, it is by design.
The `tEnv.listUserDefinedFunctions()` in Table API and `show functions;` in
SQL CLI are intended to return only the registered UDFs, not including
built-in functions.
This is also the behavior in previous versions.

Best,
Jark

[Till Rohrmann]

Thanks for reporting this issue Guowei. Could you share a bit more details
what the job exactly does and which operators it uses? Does the job uses
the new `TwoInputSelectableStreamTask` which might cause the performance
regression?

I think it is important to understand where the problem comes from before
we proceed with the release.

Cheers,
Till

[Gyula Fóra]

Hi all,
I agree with Till that we should investigate the suspected performance
regression issue before proceeding with the release.

If we do not find any problem I vote +1

I have verified the following behaviour:
 - Built flink with custom hadoop version
 - YARN Deployment with and without high-availability
 - Simulated TM and JM failures
 - Test recovery with savepoints and checkpoints for simple stateful job
with kafka connectors

Gyula

[tison]

We should investigate the performance regression but regardless the
regression I vote +1

Have verified following things

- Simulate JM and TM failures.
- Simulate temporary network partition.

Best,
tison.

[Tzu-Li (Gordon) Tai]

Hi,

https://issues.apache.org/jira/browse/FLINK-13752 turns out to be an actual
blocker, so we would have to close this RC now in favor of a new one.

Since we are already quite past the planned release time for 1.9.0, I would
like to limit the new changes included in RC3 to only the following:
- https://issues.apache.org/jira/browse/FLINK-13752
- Fix license and notice file issues that Kurt had found with
flink-runtime-web and flink-state-processing-api

This means that I will not be creating RC3 with the release-1.9 branch as
is, but essentially only cherry-picking the above mentioned changes on top
of RC2.
The minimal set of changes on top of RC2 should allow us to carry most if
not all of the already existing votes without another round of extensive
testing, and allow us to have a shortened voting time.

I understand that there are other issues mentioned in this thread that are
already spotted and merged to release-1.9, especially for the Blink planner
and DDL, but I suggest not to include them in RC3.
I think it would be better to collect all the remaining issues for those
over a period of time, and include them as 1.9.1 which can ideally also
happen a few weeks soon after 1.9.0.

What do you think? If there are not objections, I would proceed with this
plan and push out a new RC by the end of today (Aug. 19th CET).

Regards,
Gordon

Hi Gordon,

I remember we mentioned earlier that if there is an additional RC, we can
piggyback the GCP PubSub API change (
https://issues.apache.org/jira/browse/FLINK-13231). It is a small patch to
avoid future API change. So should be able to merge it very shortly. Would
it be possible to include that into RC3 as well?

Thanks,

Jiangjie (Becket) Qin

[Stephan Ewen]

+1 for Gordon's approach.

If we do that, we can probably skip re-testing everything and mainly need
to verify the release artifacts (signatures, build from source, etc.).

If we open the RC up for changes, I fear a lot of small issues will rush in
and destabilize the candidate again, meaning we have to do another larger
testing effort.

[Jark Wu-2]

Hi Gordon,

I agree that we should pick the minimal set of changes to shorten the
release testing time.
However, I would like to include FLINK-13699 into RC3. FLINK-13699 is a
critical DDL issue, and is a small change to flink table (won't affect the
runtime feature and stability).
I will do some tests around sql and blink planner if the RC3 include this
fix.

But if the community against to include it, I'm also fine with having it in
the next minor release.

Thanks,
Jark

[Timo Walther-2]

I support Jark's fix for FLINK-13699 because it would be disappointing
if both DDL and connectors are ready to handle DATE/TIME/TIMESTAMP but a
little component in the middle of the stack is preventing an otherwise
usable feature. The changes are minor.

Thanks,
Timo

[Tzu-Li (Gordon) Tai]

Thanks for the comments and fast fixes.

@Becket Qin <[hidden email]> I've quickly looked at the changes to
the PubSub connector. Given that it is a API-breaking change and is quite
local as a configuration change, I've decided to include that change in RC3.
@Jark @Timo Walther <[hidden email]> I'll be adding FLINK-13699 as well.

Quick update regarding the LICENSE issue with flink-runtime-web: I've
doubled checked this and the licenses for the new bundled Javascript
dependencies are actually already correctly present under the root
licenses-binary/ directory, so we actually don't need additional changes
for this.

I've started to create RC3 now, will post the vote as soon as it is ready.

Cheers,
Gordon
