HDP 2.6.0 includes two versions of Apache Hive, one based on the Hive 1 branch, meant for batch processing and one based on the Hive 2 branch, meant for interactive processing. Hortonworks applies stabilizations, bug fixes and features from the trunk code base as deemed appropriate, so neither of these is identical to any specific released build in Apache. Specific details on the differences are provided here.

HDP deployments driven by Apache Ambari can deploy both Hive 1 and Hive 2 side-by-side. In this setup, Hive 2 features are accessed through the Hive LLAP interface.
