Tobi Bosede commented on SPARK-10915:

Hmm...I don't think percent_rank does what I thought. It looks like it returns 
the percentile of a value rather than the value at a specific percentile, say 
25th or 75th. Really surprised spark has no quantile or percentile function in 
the traditional sense like at the below links for python.
