5 Introduction to Integration with Apache Hive

The Integration with Apache Hadoop MapReduce section describes the set of classes provided by Oracle NoSQL Database that support running Hadoop MapReduce jobs against data stored in an Oracle NoSQL Database table. Since a typical Hive query generally results in the execution of a MapReduce job, it was natural for Oracle NoSQL Database to also provide new interfaces and classes which support running Hive queries against such table data.

In addition to describing the core interfaces and classes involved in running a Hive query against data from a table located in a given Oracle NoSQL Database store, the information presented in this section will also present the steps to take to execute a given set of basic Hive queries against example table data contained in such a store, where the store can be either secure or non-secure.
