About Hive

Apache Hive is a powerful data warehousing application for Hadoop. It enables you to access your data using Hive QL, a language 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. As of CDH 5, Hive supports HCatalog which must be installed separately.

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.

  Warning: Because of concurrency and security issues, HiveServer1 and the Hive CLI is deprecated in CDH 5 and will be removed in a future release. Cloudera recommends you migrate to Beeline and HiveServer2 as soon as possible. The Hive CLI is not needed if you are using Beeline with HiveServer2.
