Re: [DISCUSS] Releasing Flink 1.9.2

[Jingsong Li]

Thanks Hequn.

+1 for starting RC of 1.9.2.
With the development of our 1.10 bug fix, we have fixed 137 issues for
1.9.2. It's worth releasing 1.9.2, which really solves a lot of urgent bugs
for users.

Re: [DISCUSS] Releasing Flink 1.9.2

[Hequn Cheng]

Hi everyone,

Considering that we are on the finishing line for release-1.10.0 and that
there are no blockers for release-1.9.2, I'm proposing to resume this
discussion.
If there are no more concerns or any critical issues for releasing 1.9.2, I
would like to create the first RC soon :)

Best,
Hequn

Re: [DISCUSS] Releasing Flink 1.9.2

[Hequn Cheng]

Hi Till,

I agree with your concerns and thanks a lot for your feedback!

In fact, I also have those concerns. The reasons I started the DISCUSS are:
- Considering the low capacities, I want to start the discussion earlier so
that we can have more time to collect information and planning for the
release. Usually, it takes a couple of weeks to address the blockers.
- The blockers of 1.9.2 are probably also blockers for 1.10.0, take
FLINK-15266 as an example. I can help to drive to solve the problem so that
1.10.0 can also benefit from it.

However, to ease the load, we can vote after Christmas if there are no more
blockers at that time.
There is a chance that the 1.10 blocker resolution has calmed down a bit.

Best,
Hequn

Re: [DISCUSS] Releasing Flink 1.9.2

[Till Rohrmann]

Hi Hequn,

thanks for starting this discussion. In general I think it is a good idea
to release often. Hence, I also believe it is time for another bug fix
release for 1.9.

The thing I'm wondering is whether we are stretching our resources a bit
too much if we now start with a 1.9.2 release vote because of the ongoing
1.10 release testing work. My concern is that we don't have the capacities
to properly test the 1.9 RC. Additionally, many people will be on Christmas
vacations during the next 2 weeks. If this is it not a problem and we have
enough resources for a parallel release then we can start it. Otherwise I'd
say that we wait until the 1.10 blocker resolution has calmed down a bit.

Cheers,
Till

[DISCUSS] Releasing Flink 1.9.2

[Hequn Cheng]

Hi everyone,

It has already been two months since we released the Flink 1.9.1.
We already have many important bug fixes from which our users can benefit
in the release-1.9 branch (85 resolved issues).
Therefore, I propose to create the next bug fix release for Flink 1.9.

Most notable fixes are:

- [FLINK-14074] MesosResourceManager can't create new taskmanagers in
Session Cluster Mode.
- [FLINK-14995] Kinesis NOTICE is incorrect
- [FLINK-15013] Flink (on YARN) sometimes needs too many slots
- [FLINK-15036] Container startup error will be handled out side of the
YarnResourceManager's main thread
- [FLINK-14315] NPE with JobMaster.disconnectTaskManager

Furthermore, there is one issue marked as blocker for 1.9.2 which should be
merged before 1.9.2 release:

- [FLINK-15266] NPE in blink planner code gen (reviewing)

If there are any other blocker issues need to be fixed in 1.9.2, please let
me know.
I will kick off the release process once blocker issues have been merged.

It would be very appreciated if there is any PMC can help with the final
steps of the release process.

Best,
Hequn
