Subject [jira] [Commented] (SPARK-14146) Imported implicits can't be found in Spark REPL in some cases
Date Mon, 02 May 2016 23:44:12 GMT

    [ https://issues.apache.org/jira/browse/SPARK-14146?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15267742#comment-15267742
] 

Wenchen Fan commented on SPARK-14146:
-------------------------------------

this is actually a scala issue: https://issues.scala-lang.org/browse/SI-9734 , and it's already
fixed. We should wait for the scala release with this bug fix.

>             Project: Spark
>          Issue Type: Bug

> {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}
