[jira] [Commented] (SPARK-10039) Resetting REPL state does not work

["Sean Owen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-10039?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14716247#comment-14716247 ] 

Sean Owen commented on SPARK-10039:
-----------------------------------

I assume this just affects 2.10 since the 2.11 build uses a much more off-the-shelf Scala shell / REPL rather than a modified fork.

Is the code in question part of what Spark modified from the 2.10 REPL -- can you tell? then indeed maybe this is just a simple bug fix. But if it's from upstream Scala code, then I wonder if this is really the problem and solution.
