Joseph K. Bradley created SPARK-7150:
----------------------------------------
Summary: Facilitate random column generation for DataFrames
Key: SPARK-7150
URL: https://issues.apache.org/jira/browse/SPARK-7150
Project: Spark
Issue Type: Improvement
Components: ML, SQL
Reporter: Joseph K. Bradley
Priority: Minor
It would be handy to have easy ways to construct random columns for DataFrames.
Proposed API:
{code}
object RandomRDD {
def normalColumn(): Column = ???
}
{code}
Usage:
{code}
myDataFrame.withColumn("myRandCol", RandomRDD.normalColumn())
{code}
This could be part of spark.ml (in which case it could be in a RandomRDD object
resembling the one in spark.mllib), or it could be in SQL proper. I'd go for
spark.ml, but either is fine with me.
