Subject [jira] [Commented] (SPARK-22393) spark-shell can't find imported types in class constructors, extends clause
Date Sun, 29 Oct 2017 20:35:00 GMT

    [ https://issues.apache.org/jira/browse/SPARK-22393?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16224194#comment-16224194
] 

Sean Owen commented on SPARK-22393:
-----------------------------------

I'm guessing it's something to do with how it overrides the shell initialization or classloader.
It could be worth trying the 2.12 build and shell as the shell integration is a little less
hacky. But really no idea off the top of my head.

>    Affects Versions: 2.0.2, 2.1.2, 2.2.0

> 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.
