Re: [VOTE] Spark 2.2.1 (RC1)

[Felix Cheung]

I wasn’t able to test this out.

Is anyone else seeing this error? I see a few JVM fixes and getting back
ported, are they related to this?

This issue seems important to hold any update until we know more.

Re: [VOTE] Spark 2.2.1 (RC1)

[Sean Owen]

The signature is fine, with your new sig. Updated hashes look fine too.
LICENSE is still fine to my knowledge.

Is anyone else seeing this failure?

FAQ


How can I help test this release?


If you are a Spark user, you can help us test this release by taking an
existing Spark workload and running on this release candidate, then
reporting any regressions.


If you're working in PySpark you can set up a virtual env and install the
current RC and see if anything important breaks, in the Java/Scala you can
add the staging repository to your projects resolvers and test with the RC
(make sure to clean up the artifact cache before/after so you don't end up
building with a out of date RC going forward).


What should happen to JIRA tickets still targeting 2.2.1?


Committers should look at those and triage. Extremely important bug fixes,
documentation, and API tweaks that impact compatibility should be worked on
immediately. Everything else please retarget to 2.2.2.


But my bug isn't fixed!??!


In order to make timely releases, we will typically not hold the release
unless the bug in question is a regression from 2.2.0. That being said if
there is something which is a regression form 2.2.0 that has not been
correctly targeted please ping a committer to help target the issue (you
can see the open issues listed as impacting Spark 2.2.1 / 2.2.2 here

.


What are the unresolved issues targeted for 2.2.1

?


At the time of the writing, there is one resolved SPARK-22471
 would help stability,
and one in progress on joins SPARK-22042

Re: [VOTE] Spark 2.2.1 (RC1)

[Felix Cheung]

Thanks Xiao, please continue to merge them to branch-2.2 and tag with
TargetVersion 2.2.2

They look to be fairly isolated, please continue to test this RC1 as much
as possible and I think we should hold on rolling another RC till Sunday.

Hi, Felix,

https://issues.apache.org/jira/browse/SPARK-22469

Maybe also include this regression of 2.2? It works in 2.1

Thanks,

If you are a Spark user, you can help us test this release by taking an
existing Spark workload and running on this release candidate, then
reporting any regressions.

If you're working in PySpark you can set up a virtual env and install the
current RC and see if anything important breaks, in the Java/Scala you can
add the staging repository to your projects resolvers and test with the RC
(make sure to clean up the artifact cache before/after so you don't end up
building with a out of date RC going forward).

*What should happen to JIRA tickets still targeting 2.2.1?*

Committers should look at those and triage. Extremely important bug fixes,
documentation, and API tweaks that impact compatibility should be worked on
immediately. Everything else please retarget to 2.2.2.

*But my bug isn't fixed!??!*

In order to make timely releases, we will typically not hold the release
unless the bug in question is a regression from 2.2.0. That being said if
there is something which is a regression form 2.2.0 that has not been
correctly targeted please ping a committer to help target the issue (you
can see the open issues listed as impacting Spark 2.2.1 / 2.2.2 here

.
