Reynold Xin created SPARK-14145:
-----------------------------------
Summary: Remove the untyped version of Dataset.groupByKey
Key: SPARK-14145
URL: https://issues.apache.org/jira/browse/SPARK-14145
Project: Spark
Issue Type: Sub-task
Components: SQL
Reporter: Reynold Xin
Assignee: Reynold Xin
Dataset has two variants of groupByKey, one for untyped and the other for
typed. It actually doesn't make as much sense to have an untyped API here,
since apps that want to use untyped APIs should just use the groupBy
"DataFrame" API.
