## What changes were proposed in this pull request? `HintInfo.isBroadcastable` is actually not an accurate name, it's used to force the planner to broadcast a plan no matter what the data size is, via the hint mechanism. I think `forceBroadcast` is a better name. And `isBroadcastable` only have 2 possible values: `Some(true)` and `None`, so we can just use boolean type for it. ## How was this patch tested? existing tests. Author: Wenchen Fan <wenchen@databricks.com> Closes #18189 from cloud-fan/stats.
## What changes were proposed in this pull request? Removed a duplicate case in "SPARK-20854: select hint syntax with expressions" ## How was this patch tested? Existing tests. Author: Bogdan Raducanu <bogdan@databricks.com> Closes #18217 from bogdanrdc/SPARK-20854-2.
## What changes were proposed in this pull request? We had better update the deprecation notes about Python 2.6, Hadoop (before 2.6.5) and Scala 2.10 in [2.2.0-RC4](http://people.apache.org/~pwendell/spark-releases/spark-2.2.0-rc4-docs/) documentation. Since this is a doc only update, I think we can update the doc during publishing. **BEFORE (2.2.0-RC4)**  **AFTER**  ## How was this patch tested? Manual. ``` SKIP_API=1 jekyll build ``` Author: Dongjoon Hyun <dongjoon@apache.org> Closes #18207 from dongjoon-hyun/minor_doc_deprecation.
