            </div>
            <p>
                Apache Hive is a distributed, fault-tolerant data warehouse system that enables analytics at a massive scale.
                Hive Metastore(HMS) provides a central repository of metadata that can easily be analyzed to make informed,
                data driven decisions, and therefore it is a critical component of many data lake architectures.

                Hive is built on top of Apache Hadoop and supports storage on S3, adls, gs etc though hdfs.
                Hive allows users to read, write, and manage petabytes of data using SQL.

                <p>
                    The Hive Metastore (HMS) is a central repository of metadata for Hive tables and partitions in a relational database,
                    and provides clients (including Hive, Impala and Spark) access to this information using the metastore service API.
                    It has become a building block for data lakes that utilize the diverse world of open-source software, such as Apache Spark and Presto.
                    In fact, a whole ecosystem of tools, open-source and otherwise, are built around the Hive Metastore, some of which this diagram illustrates.
