----------------------------------
Summary: Ability to select first row of groupby
Key: SPARK-19428
URL: https://issues.apache.org/jira/browse/SPARK-19428
Project: Spark
Issue Type: Brainstorming
Components: SQL
Affects Versions: 2.1.0
Reporter: Luke Miner
Priority: Minor
It would be nice to be able to select the first row from {{GroupedData}}.
Pandas has something like this:
{{df.groupby('group').first()}}
It's especially handy if you can order the group as well.
