Thanks Nick, Hyukjin. Yes this seems to be a longer standing issue on RHEL with respect to

Subject: Re: [VOTE] Spark 2.1.2 (RC4)

Ah yes - I recall that it was fixed. Forgot it was for 2.3.0

My +1 vote stands.

Hi Nick,

I believe that R test failure is due to SPARK-21093, at least the error message looks the
same, and that is fixed from 2.3.0. This was not backported because I and reviewers were worried
as that fixed a very core to SparkR (even, it was reverted once even after very close look
by some reviewers).

I asked Michael to note this as a known issue in
before due to this reason.
I believe It should be fine and probably we should note if possible. I believe this should
not be a regression anyway as, if I understood correctly, it was there from the very first

Checked sigs & hashes.

Tested on RHEL
build/mvn -Phadoop-2.7 -Phive -Pyarn test passed
Python tests passed

I ran R tests and am getting some failures:
(I seem to recall similar issues on a previous release but I thought it was fixed).

I re-ran R tests on an Ubuntu box to double check and they passed there.

So I'd still +1 the release

Perhaps someone can take a look at the R failures on RHEL just in case though.

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so you don't end up building with a out of date RC going forward).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 2.1.2?

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 2.1.3.

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 2.1.1. That being said if there is something which is a regression
form 2.1.1 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 2.1.1 & 2.1.2<>)

What are the unresolved issues targeted for 2.1.2<>?

At this time there are no open unresolved issues.

Is there anything different about this release?

This is the first release in awhile not built on the AMPLAB Jenkins. This is good because
it means future releases can more easily be built and signed securely (and I've been updating
the documentation in as I progress), however
the chances of a mistake are higher with any change like this. If there something you normally
take for granted as correct when checking a release, please double check this time :)

Should I be committing code to branch-2.1?

Thanks for asking! Please treat this stage in the RC process as "code freeze" so bug fixes
only. If you're uncertain if something should be back ported please reach out. If you do commit
to branch-2.1 please tag your JIRA issue fix version for 2.1.3 and if we cut another RC I'll
move the 2.1.3 fixed into 2.1.2 as appropriate.

What happened to RC3?

Some R+zinc interactions kept it from getting out the door.
