Mark Petruska commented on SPARK-22393:
---------------------------------------
[~srowen], [~rdub], I can now confirm that the original bug fix that was pushed
to Scala 2.12 fixes this issue. Succeeded in retrofitting the same changes into
Spark-shell, see: https://github.com/apache/spark/pull/19846.
The original fix for Scala 2.12 can be found at:
https://github.com/scala/scala/pull/5640
The downside is that the code/fix is not the most approachable, could not
refactor for better readability (and also making sure it compiles :) ).
> spark-shell can't find imported types in class constructors, extends clause

> Key: SPARK-22393
> URL: https://issues.apache.org/jira/browse/SPARK-22393
> Project: Spark
> Issue Type: Bug
> Components: Spark Shell
> Affects Versions: 2.0.2, 2.1.2, 2.2.0
> Reporter: Ryan Williams
> Priority: Minor
>
> {code}
> $ spark-shell
> …
> scala> import org.apache.spark.Partition
> import org.apache.spark.Partition
> scala> class P(p: Partition)
> <console>:11: error: not found: type Partition
> class P(p: Partition)
> ^
> scala> class P(val index: Int) extends Partition
> <console>:11: error: not found: type Partition
> class P(val index: Int) extends Partition
> ^
> {code}
> Any class that I {{import}} gives "not found: type ___" when used as a
> parameter to a class, or in an extends clause; this applies to classes I
> import from JARs I provide via {{--jars}} as well as core Spark classes as
> above.
> This worked in 1.6.3 but has been broken since 2.0.0.
