Hive is a popular data warehouse solution running on top of Hadoop, while Shark is a system that allows the Hive framework to run on top of Spark instead of Hadoop. As a result, Shark can accelerate Hive queries by as much as 100x when the input data fits into memory, and up 10x when the input data is stored on disk.

It provides an SQL-like language called HiveQL with schema on read and transparently converts queries to Hadoop MapReduce, Apache Tez and Apache Spark jobs.

Despite all the great things Hive can solve, this post is to talk about why we move our ETL’s to the ‘not so new’ player for batch processing, Spark.
