What are the advantages of Apache Pig?
a. Advantages of Apache Pig
- Less development time.
- Easy to learn.
- Procedural language.
- Easy to control execution.
- Lazy evaluation.
- Usage of Hadoop features.
What are some of the benefits of Hadoop abstractions such as Pig and Hive over MapReduce?
Pig and Hive provide higher level of abstraction whereas Hadoop MapReduce provides low level of abstraction. Hadoop MapReduce requires more lines of code when compared to Pig and Hive. Hive requires very few lines of code when compared to Pig and Hadoop MapReduce because of its SQL like resemblance.

In addition, it has a lot of relational database features. Moreover, commands like good old joins, distinct, union and many more are already in the language.
What is pig in database?
Pig is a high-level platform or tool which is used to process the large datasets. It provides a high-level of abstraction for processing over the MapReduce.
