Component Versions
The official Apache versions of most HDP 2.3.4 components are unchanged from HDP 2.3.0.0, with the exception of Spark and Kafka. Spark is upgraded from 1.4.1 to 1.5.2; Kafka is upgraded from 0.8.2 to 0.9.0. See more details of Spark 1.5.2 and Kafka 0.9.0 in the New Features section. All HDP 2.2 components listed here are official Apache releases of the most recent stable versions available.
Hortonworks’ philosophy is to provide patches only when absolutely necessary to assure the interoperability of the components. Unless you are explicitly directed by Hortonworks Support to take a patch update, each of the HDP components should remain at the following package version levels to ensure a certified and supported copy of HDP 2.3.4.
