*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building with a out of date RC going forward).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 the time of the writing, there is one in progress major issue SPARK-21985
<>, I believe Andrew Ray &
HyukjinKwon are looking into this one.
