Subject [jira] [Commented] (HBASE-16179) Fix compilation errors when building hbase-spark against Spark 2.0
Date Tue, 27 Sep 2016 21:34:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16179?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15527475#comment-15527475

Sean Busbey commented on HBASE-16179:
-------------------------------------

So you'd like us to just mandate Scala 2.10 for both 1.6 and 2.0, right?

Reading through the threads when dev@spark talks about scala versions I got the sense that
Scala 2.10 won't be long for the 2.y line. When that time comes, what would we do? I'm not
necessarily asking that we address this now, just want to know that we've thought of a general
approach to supportability. We haven't taken a stance as a community yet on support timelines
for Scala versions, but I'd expect we'd treat them similar to JDK versions, which would means
we'd keep a Scala 2.10 based Spark 2 module for the remainder of HBase 2.y.

> I tried building hbase-spark module against Spark-2.0 snapshot and got the following
compilation errors:

> Some Spark classes such as DataTypeParser and Logging are no longer accessible to downstream
projects.
> hbase-spark module should not depend on such classes.
