Subject [jira] [Commented] (SPARK-18134) SQL: MapType in Group BY and Joins not working
Date Thu, 24 Nov 2016 15:17:58 GMT

    [ https://issues.apache.org/jira/browse/SPARK-18134?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15693519#comment-15693519
] 

Herman van Hovell commented on SPARK-18134:
-------------------------------------------

[~ChrisZ84] The current PR a proof of concept, and not a complete solution. We first need
to discuss if this is the right approach.

We are currently deep in the QA period for Spark 2.1, RC1 should be close. This means that
this will be slated for 2.2.

> 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.
