Herman van Hovell commented on SPARK-18134: ------------------------------------------- Maps are not comparable. This makes them unusable as a join and grouping keys. We generally try to be as compatible with Hive as we can be, but in this case I am not sure that we should do this. > 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 > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
