Difference between Pig and Hive? Why have both? [closed]

Answer 1

Hive Vs Pig-

Hive is as SQL interface which allows sql savvy users or Other tools like Tableu/Microstrategy/any other tool or language that has sql interface..

PIG is more like a ETL pipeline..with step by step commands like declaring variables, looping, iterating , conditional statements etc.

I prefer writing Pig scripts over hive QL when I want to write complex step by step logic. When I am comfortable writing a single sql for pulling the data i want i use Hive. for hive you will need to define table before querying(as you do in RDBMS)

The purpose of both are different but under the hood, both do the same, convert to map reduce programs.Also the Apache open source community is add more and more features to both there projects
