TobiasP created SPARK-16823:
-------------------------------
Summary: One dimensional typed select on DataFrame does not work
as expected
Key: SPARK-16823
URL: https://issues.apache.org/jira/browse/SPARK-16823
Project: Spark
Issue Type: Bug
Reporter: TobiasP
Priority: Minor
{code}
spark.sqlContext.createDataFrame(for { x <- 1 to 4; y <- 1 to 4 } yield ((x,
y),x)).select($"_1".as[(Int,Int)], $"_2".as[Int])
{code}
works, so I would expect
{code}
spark.sqlContext.createDataFrame(for { x <- 1 to 4; y <- 1 to 4 } yield ((x,
y),x)).select($"_1".as[(Int,Int)])
{code}
to work too, but it expects a wrapping type around the tuple.
