*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building with a out of date RC going forward).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.

*Why the longer voting window?*

Since there is a large industry big data conference this week I figured I'd
add a little bit of extra buffer time just to make sure everyone has a
chance to take a look.
