Installing HDF Services on an Existing HDP Cluster
Also available as:

Before you Begin


If you are using JDK1.7 (which was deprecated in HDP 2.6.0), you will need to add a custom parameter (ranger.tomcat.ciphers) to your ranger configuration (ranger-admin-site and ranger-kms-site) before upgrading to HDP 2.6.1. This is applicable for fresh installs as well (only when using JDK 1.7).
