[DISCUSS] Releasing Flink 1.9.1

[Jark Wu-2]

Hi everyone,

It has already been a month since we released Flink 1.9.0.
We already have many important bug fixes from which our users can benefit
in the release-1.9 branch (83 resolved issues).
Therefore, I propose to create the next bug fix release for Flink 1.9.

Most notable fixes are:

- [FLINK-13526] When switching to a non existing catalog or database in the
SQL Client the client crashes.
- [FLINK-13568] It is not possible to create a table with a "STRING" data
type via the SQL DDL.
- [FLINK-13941] Prevent data-loss by not cleaning up small part files from
S3.
- [FLINK-13490][jdbc] If one column value is null when reading JDBC, the
following values will all be null.
- [FLINK-14107][kinesis] When using event time alignment with the Kinsesis
Consumer the consumer might deadlock in one corner case.

Furthermore, I would like the following critical issues to be merged before
1.9.1 release:

- [FLINK-14118] Reduce the unnecessary flushing when there is no data
available for flush which can save 20% ~ 40% CPU. (reviewing)
- [FLINK-13386] Fix A couple of issues with the new dashboard have already
been filed. (PR is created, need review)
- [FLINK-14010][yarn] The Flink YARN cluster can get into an inconsistent
state in some cases, where
leaderhship for JobManager, ResourceManager and Dispatcher components is
split between two master processes. (PR is created, need review)

I would volunteer as release manager and kick off the release process once
blocker issues has been merged. What do you think?

If there is any other blocker issues need to be fixed in 1.9.1, please let
me know.

Cheers,
Jark

FLINK-13708 is also very critical IMO. This would cause invalid flink job
(doubled output)

[Jark Wu-2]

Thanks Till for reviewing FLINK-14010.

Hi Jeff, I think it makes sense to merge FLINK-13708 before the release (PR
has been reviewed).

Hi Debasish, FLINK-12501 has already been merged in 1.10.0. I'm fine to
cherry-pick it to 1.9 if we
have a consensus this issue could be viewed as a bug. We can continue the
discussion in the JIRA.

Best,
Jark

+1 for 1.9.1 soon :)

I would also like to include a fix to:
FLINK-14145 - getLatestCheckpoint(true) returns wrong checkpoint

It is already merged to master and just need to merge it to 1.9 if we all
agree (https://github.com/apache/flink/pull/9756)

Cheers,
Gyula

[Jark Wu-2]

Hi all,

I am here to update the progress of the issue that needs to be tracked:

- FLINK-14010 (merged)
- FLINK-14118 (under discussion whether we should back port it to 1.9)
- FLINK-13386 (Daryl reviewed and Dawid will verify the functionality again)
- FLINK-13708 (under reviewing)
- FLINK-14145 (merged to master and need to merge it to 1.9 if we all agree)

Great thanks to all of you for helping fix and reviewing!
Ideally, we can kick off the release vote for the first RC early next week.

Best,
Jark

Could you help to create 1.9.2 release version in JIRA when you are free?

Best,
Jark

[Jark Wu-2]

Hi all,

I am here to update the progress of the issues that need to be tracked:

- FLINK-14010 (merged)
- FLINK-13386 (merged)
- FLINK-14145 (merged)
- FLINK-14118 (not back port to 1.9)
- FLINK-13708 (as discussed with Jeff offline, postpone it to 1.9.2)

Great thanks to all of you for helping fix and reviewing!  All the blocker
issues for 1.9.1 has been resolved.
Thanks @Jincheng for creating 1.9.2 version in JIRA.
I'll proceed to create the first release candidate for 1.9.1 now then.

Cheers,
Jark

Hi Debasish,

+1 have FLINK-12501 in 1.9.1. As there is nobody against it under the JIRA

Jark
