Christian Zorneck created SPARK-18134:
-----------------------------------------
Summary: 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: 2.0.1, 2.0.0, 1.6.2, 1.6.1, 1.6.0, 1.5.2, 1.5.1, 1.5.0
Reporter: Christian Zorneck
Priority: Blocker
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.
