[jira] [Created] (SPARK-19428) Ability to select first row of groupby

Luke Miner created SPARK-19428:
----------------------------------

             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.
