This is a basic Ambari blueprint for clusters that implement high availability for HDFS, Yarn and Hive for HDP 2.6. This includes Namenode HA, Resourcemanager HA, Hive Metastore server HA and Hive Server HA. It does not implement a high-availability database for the Hive metastore, though, as that is done within the relational database backed itself. It has been developed and tested using Cloudbreak, but should work with Ambari as well.
