Upgrading from HDP 2.4.x to HDP 2.4.2
Hortonworks Data Platform (HDP) 2.4.2 is a feature-bearing maintenance release of HDP 2.4.x; it includes changes to HDP 2.4.x beyond a standard maintenance release. These Release Notes include abbreviated upgrade instructions; for full upgrade instructions, use the Non-Ambari Upgrade Guide. If you already have HDP 2.4.x installed, upgrading your cluster to HDP 2.4.2 means:
Keeping the same configuration files you used for HDP 2.4.x
Keeping the same data and metadata in the same location you used for HDP 2.4.x
Installing any new components (added for the first time in HDP 2.4.2) side-by-side with existing components
