Apache Component Support
Hortonworks Cybersecurity Platform (HCP) 1.5.1 is built on HDP 2.6.4 and HDF 18.104.22.168 and later.
Apache Metron 0.5.0
All components listed are official Apache releases of the most recent stable versions available.
The Hortonworks approach is to provide patches only when necessary, to ensure the interoperability of components. Unless you are explicitly directed by Hortonworks Support to take a patch update, each of the HCP components should remain at the following package version levels, to ensure a certified and supported copy of HCP 1.5.1.
