Wenchen Fan updated SPARK-14146:
--------------------------------
Description:
{code}
class I(i: Int) {
def double: Int = i * 2
}
class Context {
implicit def toI(i: Int): I = new I(i)
}
val c = new Context
import c._
// OK
1.double
// Fail
class A; 1.double
{code}
The above code snippets can work in Scala REPL however.
This will affect our Dataset functionality, for example:
{code}
class A; Seq(1 -> "a").toDS() // fail
{code}
or in paste mode:
{code}
:paste
class A
Seq(1 -> "a").toDS() // fail
{code}
was:
{code}
class I(i: Int) {
def double: Int = i * 2
}
class Context {
implicit def toI(i: Int): I = new I(i)
}
val c = new Context
import c._
// OK
1.double
// Fail
class A; 1.double
{code}
The above code snippets can work in Scala REPL however.
