Hive is a data warehouse solution that is developed on top of Apache Hadoop and is used to provide data query and analysis functionality. HDFS is used to store large amounts of data matching to hive tables. Is it possible for Hive to store metadata information in HDFS? If not, where does the metadata information get stored, and how does it get stored in the first place?

Fundamentals of Datawarehouse

A data warehouse is a data repository which is used to store large quantities of historical data that are mostly used for creating reports that help businesses to identify their weaknesses and strengths. For example, demographics data about people of a region can help businesses identify the needs and preferences of the region’s population. A data warehouse acts as a central storage for storing data that comes from one or more heterogenous sources. It also consists of data which can be old and of historical value. One of the most important applications of this type of system is that it is used for supporting business intelligence and data analytics applications.
