Hi Can we use a cobination of Hive and MapReduce Say: I am having a csv file. Ineed to find the mean of a column and replace the null data with the mean(replace null with mean) so whether we can write a hive query in driver (to find the mean) then write a mapreduce block to replace the null with mean.
Which is better way 1. writing only mapreduce code or 2. Use a combination of hive and mapreduce. -- *Thanks & Regards* Unmesha Sreeveni U.B Junior Developer http://www.unmeshasreeveni.blogspot.in/
