[jira] [Commented] (SPARK-25075) Build and test Spark against Scala 2.13

    [ https://issues.apache.org/jira/browse/SPARK-25075?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16981173#comment-16981173 ] 

Sean R. Owen commented on SPARK-25075:
--------------------------------------

Yeah this change will be tricky but not terrible. One challenge is that until one can get the whole project to compile, it's hard to know all the issues. I've fixed a few obvious ones, and will file a few more classes of issue I've found.

The major change is indeed the Seq / Map change. That's solved with a lot of .toSeq and .toMap across the project. I'm going to wait until branch-3.0 is cut to deal with that in one big change.

In the meantime, I've been making that change steadily throughout the project and have uncovered some more issues I'll file as subtasks.
