About Hive
Apache Hive is a powerful data warehousing application built on top of Hadoop; it enables you to access your data using Hive QL, a language that is similar to SQL.
Install Hive on your client machine(s) from which you submit jobs; you do not need to install it on the nodes in your Hadoop cluster.
HiveServer2
HiveServer2 is an improved version of HiveServer that supports a Thrift API tailored for JDBC and ODBC clients, Kerberos authentication, and multi-client concurrency. The CLI for HiveServer2 is Beeline.
