Answer / Shailja Singh
Pig and MapReduce are related, but they differ in several aspects. While MapReduce is a low-level programming model for processing large datasets, Pig provides a high-level data flow abstraction on top of MapReduce to make it easier for non-expert programmers to analyze large datasets. In addition, Pig supports user-defined functions (UDFs) and built-in functions that make it more flexible in handling various data manipulation tasks.
