When I looked at this last fall, the only way that seemed to be available was to transform
my data into SchemaRDDs, register them as tables and then use the Hive processor to calculate
them with its built in percentile UDFs that were added in 1.2.

Is there any inbuilt function for calculating percentile over a dataset ?

I want to calculate the percentiles for each column in my data.
