Since my original email, I've talked to a lot more users and looked at what
various environments support. It is true that a lot of enterprises, and
even some technology companies, are still using Java 7. One thing is that
up until this date, users still can't install openjdk 8 on Ubuntu by
default.
Works for me on latest master.

Hi,
Based on master branch refreshed today, I issued 'git clean -fdx' first.
Then this command:
build/mvn clean -Phive -Phive-thriftserver -Pyarn -Phadoop-2.6
-Dhadoop.version=2.7.0 package -DskipTests
I got the following error:

Hi,
(since 2.0.0-SNAPSHOT it's more for dev not user)
With today's master I'm getting the following:
scala> ds
res14: org.apache.spark.sql.Dataset[(String, Int)] = [_1: string, _2: int]
// WHY?!
scala> ds.groupBy(_._1)
:26: error: missing parameter type for expanded function
((x$1) => x$1._1)
