-------------------------------------
[~hvanhovell]- What is the state of this JIRA? Do we expect to make progress on
this any time soon? This is a very critical feature we are missing in Spark
which is blocking us from auto-migrating HiveQL to Spark. Please let us know if
anything we can do to help resolve this issue.

> SQL: MapType in Group BY and Joins not working
> ----------------------------------------------
>
> 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,
> 2.1.0
> Reporter: Christian Zorneck
> Priority: Major
>
> 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.
