What is Apache Hive?
Apache Hive is a distributed, fault-tolerant data warehouse system that enables analytics at a massive scale. A data warehouse provides a central store of information that can easily be analyzed to make informed, data driven decisions. 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. What makes Hive unique is the ability to query large datasets, leveraging Apache Tez or MapReduce, with a SQL-like interface.
The following component diagram depicts the architecture of Apache Hive:

Why Monitor Apache Hive?
In mission critical environments, even the slightest of deficiencies in the performance of the data warehouse if not detected promptly and resolved quickly, can result in irredeemable loss of critical data. To avoid such data loss and to ensure availability of data round the clock, the Apache Hive should be monitored periodically. For this purpose, eG Enterprise offers a specialized Apache Hive monitoring model.
By closely monitoring the target Apache Hive, administrators can be proactively alerted to issues in the overall performance and critical operations of the Apache Hive data warehouse, identify serious issues and plug the holes before any data loss occurs.
