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) <console>:26: error: missing parameter type for expanded function ((x$1) => x$1._1) ds.groupBy(_._1) ^ scala> ds.filter(_._1.size > 10) res23: org.apache.spark.sql.Dataset[(String, Int)] = [_1: string, _2: int] It's even on the slide of Michael in https://youtu.be/i7l3JQRx7Qw?t=7m38s from Spark Summit East?! Am I doing something wrong? Please guide.
