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and test with the RC (make sure to clean up the artifact cache before/after so you don't end up building with a out of date RC going forward).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 https://github.com/apache/spark-website/pull/66 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.
