[jira] [Commented] (SPARK-18134) SQL: MapType in Group BY and Joins
not working
[ https://issues.apache.org/jira/browse/SPARK-18134?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15663394#comment-15663394 ]
Christian Zorneck commented on SPARK-18134:
-------------------------------------------
Is there some hope, this issue will be fixed? For us, it is a very important feature, and without it, we can not migrate to a newer AWS EMR version.

> Key: SPARK-18134
> URL: https://issues.apache.org/jira/browse/SPARK-18134
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.5.0, 1.5.1, 1.5.2, 1.6.0, 1.6.1, 1.6.2, 2.0.0, 2.0.1
> Reporter: Christian Zorneck

> Since version 1.5 and issue SPARK-9415, MapTypes can no longer be used in GROUP BY and join clauses. This makes it incompatible to HiveQL. So, a Hive feature was removed from Spark. This makes Spark incompatible to various HiveQL statements.
