-1 (non-binding) I tested it on Ubuntu 16.04 and openjdk8 on ppc64le. I got several errors. I expect that this backport (https://github.com/apache/spark/pull/17509) will be integrated into Spark 2.1.1.

The release files, including signatures, digests, etc. can be found at: http://home.apache.org/~pwendell/spark-releases/spark-2.1.1-rc2-bin/ Release artifacts are signed with the following key: https://people.apache.org/keys/committer/pwendell.asc The staging repository for this release can be found at: https://repository.apache.org/content/repositories/orgapachespark-1227/ The documentation corresponding to this release can be found at: http://people.apache.org/~pwendell/spark-releases/spark-2.1.1-rc2-docs/ 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. What should happen to JIRA tickets still targeting 2.1.1? 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 2.1.2 or 2.2.0. 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 2.1.0. What happened to RC1? There were issues with the release packaging and as a result was skipped.
