>
> Median and Mode are essential functions for reducing/refining the data set,
> and would allow for greater control over the selection of data. More involved
> analytics are probably best handled by relational databases or OLAP cubes,
> but Median and Mode are very practical for Hive solely in terms of delivering
> a smaller data set, where items selected only have a certain mode. (Rows that
> describe an object to which the table is joined where that object has a
> column value frequency threshold.)
> Comments are more than welcome. Would be happy to support.
