Subject [jira] [Commented] (SPARK-18134) SQL: MapType in Group BY and Joins not working
Date Mon, 14 Nov 2016 11:15:58 GMT

    [ https://issues.apache.org/jira/browse/SPARK-18134?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15663503#comment-15663503

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

This is a non-trivial change. Could you explain me your use case? There might be a valid work
around (using structs or arrays).

>             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

> 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.
