[jira] [Commented] (HIVEMALL-313) Why Hivemall remove spark module
in the new version? How to use function created by xxxWrapper class with
latest version?
[ https://issues.apache.org/jira/browse/HIVEMALL-313?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17343788#comment-17343788 ]
Makoto Yui commented on HIVEMALL-313:
-------------------------------------
Spark module is removed because hard to catch up frequent spark version updates and the committer for Spark module was not so active.
[https://github.com/apache/incubator-hivemall/blob/v0.5.2/spark/spark-2.3/extra-src/hive/src/main/scala/org/apache/spark/sql/hive/HiveShim.scala]
Thus, we currently just support SparkSQL (SQLContext) and no support for Dataframes.
You can fork hivemall spark modules if you want.

> -------------------------------------------------------------------------------------------------------------------------
>
> Key: HIVEMALL-313
> URL: https://issues.apache.org/jira/browse/HIVEMALL-313
> Project: Hivemall
> Issue Type: Wish
> Affects Versions: 0.6.2
> Reporter: Bob
> Priority: Major
>
> It seems that we need to create some specific functions based on xxxWrapper class in spark environment. But the latest version of Hivemall does not contain spark module any more.
> That means I have to get the previous version such as 0.5.2.
> Sometimes I have to use function A based on hivemall-spark2.2-0.5.2-incubating-with-dependencies.jar and function B based on hivemall-all-0.6.2-incubating-SNAPSHOT.jar.
> Then I may meet some dependency package conflict problems there.
> I just wonder if I could use those xxxWrapper class with Hivemall under the latest version.
> Thanks a lot for your help.
