Getting started with Hive with Kerberos.

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. If Kerberos authentication is used, authentication is supported between the Thrift client and HiveServer2, and between HiveServer2 and secure HDFS.
