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.
Pozdrawiam,
Jacek Laskowski
