             Summary: Random number generators for DataFrames
                 Key: SPARK-7248
                 URL: https://issues.apache.org/jira/browse/SPARK-7248
             Project: Spark
          Issue Type: New Feature
          Components: SQL
            Reporter: Xiangrui Meng

This is an umbrella JIRA for random number generators for DataFrames. The initial set of RNGs would be `rand` and `randn`, which takes a seed.

{code}
df.select("*", rand(11L).as("rand"))
{code}

Where those methods should live is TBD.
