Hive is a data warehousing tool built on top of Hadoop. Learn how to easily query and analyze your Big Data projects with this free Apache Hive course.
About this Course
Writing MapReduce programs to analyze your Big Data can get complex. Hive can help make querying your data much easier. Apache Hive, first created at Facebook, is a data warehouse system for Hadoop that facilitates easy data summarization, ad-hoc queries, and the analysis of large datasets stored in Hadoop compatible file systems. Hive provides a mechanism to project structure onto this data and query the data using a SQL-like language called HiveQL. This course will get you started so that you can use Hive for Data Warehousing tasks on your Big Data projects.
