---------------------------------
Possibly related too https://issues.apache.org/jira/browse/SPARK-10785 (if
could do exact rather than sampling for finding the splits and switch to
multi-column) I think it would serve this purpose well.
> Add Histogram support to Spark SQL/DataFrames
> ---------------------------------------------
>
> Key: SPARK-12185
> URL: https://issues.apache.org/jira/browse/SPARK-12185
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Reporter: holdenk
> Priority: Minor
>
> While we have the ability to compute histograms on RDDs of Doubles it would
> be good to also directly support histograms in Spark SQL (see
> https://cwiki.apache.org/confluence/display/Hive/StatisticsAndDataMining#StatisticsAndDataMining-histogram_numeric():Estimatingfrequencydistributions
> ).
