@Anurag Mishra Thanks for the detailed steps, but will snapshot take cares of DDLs too? or do we need to take a DDL and create it manually in the destination cluster? Thanks, Dhiraj.

Hi Lunesa, As you mentioned, you can use 1 server for Ambari Operation Server. 3 Servers for Master Services and 3 for DataNode and Node Manager. If you are planning to setup HA for NameNode and Resource Manager and installing core Hadoop services then you can use a similar model, You can add one more server, in case if you need standalone Ambari views or server for all Hadoop clients. I am planning to use below model to setup sandbox environment. Server 1. Ambari Server Server 2. Active NameNode, Standby Resource Manager, Journal Node, Zookeeper Server, ZKFailoverController. Server 3. Standby NameNode, Active Resource Manager, History Server, App Timeline Server, Journal Node, Zookeeper Server, ZKFailoverController. Server 4. HiveServe2, Hive Metastore, JournalNode, Zookeeper Server, WebHcat Server etc. Server 5. DataNode, NodeManager and other slave components. Server 6. DataNode, NodeManager and other slave components. Server 7. DataNode, NodeManager and other slave components. Server 8: Standalone Ambari Views Server and all Hadoop Clients (Clients like HDFS, Hive etc). (Additional Server) Explore Hortonworks documents on how to setup Ambari and HDP cluster: https://docs.hortonworks.com/ Thanks, Dhiraj.

Reason for format ZKFC is, Adding service rpc port property in NN: Please look for service rpc port in below link. https://community.hortonworks.com/articles/43838/scaling-the-hdfs-namenode-part-1.html

To reset ZKFC we have to stop both the ZKFC processes and run the following command as the hdfs super user : hdfs zkfc –formatZK Is this same for Kerberos enabled environment? Do we need to stop all HDFS Services and failover control? Where do we need to run this command in NN or anywhere? HDP Version - 2.4.3 Thanks in advance.

As I know delegate admin user cannot add new policy for new paths but can add more paths under the main path for Ranger policy. My Question is, Can delegate admin user will able to manage "selecting and changing user/group and permissions" in Ranger policy ?
