| MapReduce program expects the programming language skills for writing the business logic. |
In Apache PIG there is no need of much programming skills. The entire program is based on PIG transformations. |
| Amount of code is very large; we must write huge programming code. |
Amount of code is very less when compared to MapReduce program. 200 lines of MapReduce program is equivalent to 10 lines of Pig script. |
| MapReduce program is compiled and executed directly. |
Pig script internally converts into MapReduce program and gets executed. |
| Writing and executing MapReduce programming is a bit complex task. |
