How hive is different from pig in Hadoop?
1) Hive Hadoop Component is used mainly by data analysts whereas Pig Hadoop Component is generally used by Researchers and Programmers. 2) Hive Hadoop Component is used for completely structured Data whereas Pig Hadoop Component is used for semi structured data.
What is Hadoop Hive used for?
Hive allows users to read, write, and manage petabytes of data using SQL. Hive is built on top of Apache Hadoop, which is an open-source framework used to efficiently store and process large datasets. As a result, Hive is closely integrated with Hadoop, and is designed to work quickly on petabytes of data.
Does Pig differ from MapReduce and hive if yes how?
Yes, Pig differs from MapReduce because, in MapReduce, the group by operation is performed at reducer side and filter, and also in the map phase the projection is implemented. Pig Latin provides the operations that are similar to MapReduce, such as groupby, orderby, and filters.

What is pig in Hadoop?
What is Pig in Hadoop? Pig is a scripting platform that runs on Hadoop clusters, designed to process and analyze large datasets. Pig uses a language called Pig Latin, which is similar to SQL. This language does not require as much code in order to analyze data.
What is hive Hadoop?

What are the most important components of Hadoop?
Pig, as well as Hive, is considered as the two most essential components of the Hadoop ecosystem. Just like SQL, Hadoop is also a tried and tested tool for its performance and analysis when it comes to Big Data.
