----------------------------------
Summary: Cannot create ExpressionEncoder for Array[T] where T is a
nested class
Key: SPARK-12131
URL: https://issues.apache.org/jira/browse/SPARK-12131
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.6.0
Reporter: Cheng Lian
Assignee: Cheng Lian
The following snippet reproduces this issue under {{spark-shell}}:
{noformat}
import sqlContext._
case class N(i: Int)
case class T(a: Array[N])
val ds = Seq(T(Array(N(1)))).toDS
ds.show()
{noformat}
Note that, classes defined in Scala REPL are inherently nested.
