Ad hoc analysis using Hive


Historically, Hive was considered a good abstraction over MapReduce and for data extraction in batch mode. Hive was not considered as a good alternative for low latency queries; however, this is changing as you read this book. With Hive Version 13, you can run Hive over Apache Tez, which is faster and more efficient than the traditional MapReduce. This allows business users to explore and interact with data in HDInsight using BI tools such as Excel.
