jian wang commented on DATAFU-16:
---------------------------------

According to Matt's feedback on review request 
https://reviews.apache.org/r/17058/, need to re-think how we implement the 
reservoir sample with exponential jumps. Will do an offline simulation by this 
weekend.

> Create a weightedReservoirSampleWithExpJump UDF to implement the weighted 
> reservoir sampling algorithm with exponential jumps. Investigation is tracked 
> in  https://github.com/linkedin/datafu/issues/80. This task is part of 
> experiment of different weighted sampling algorithms.
