How to add clusters using Ambari on HDP 2.6.4
The steps will be same as older versions. Like : https://www.youtube.com/watch?v=wHaVBoLwzwU&t=1026s
Start ambari Server and then login to ambari UI.
It will show the Cluster Creation Wizard. You can follow the on screen instructions. https://docs.hortonworks.com/HDPDocuments/Ambari-184.108.40.206/bk_ambari-installation/content/ch_Deploy_an...
Currently you can only have one cluster (Local Cluster).
However Ambari allows to add multiple "Remote Clusters" (Means ambari can point to a remote ambari cluster)
Installed Hadoop Sandbox with Ambari. One VM, when I login as admin, and go to the manage Ambari I do not see the cluster wizard to create clusters. The book I am using says there should be 4 nodes (limulus, n0, n1, and n2).
If you are usijng "Hadoop Sandbox" (Provided by Hortonworks) then it already has the cluster pre configured for single node machine. So you will not see the cluster setup wizard.
If you readdy want to see the cluster creation wizard then you will need a fresh Ambari Server with clean DB. Or you will have to RESET the ambari DB so that the existing cluster information is gone.
# pg_dump -U ambari ambari > /tmp/ambari_db_dump.sql Password: bigdata
The following will cause the complete Data Loss for Ambari Cluster:
# ambari-server stop # ambari-server reset # ambari-server start
Thanks! I am an educator and I want to show my students Hadoop with a few clusters. I can delete what I built and start over.
1. Is there a sandbox download from HortonWorks that has a fresh Ambari so I can use it to create clusters
Should I install a Sandbox VM for each cluster or all are created on one VM
2, If I want to use your codes to reset the Ambari, should I put those code in the the built-in web client at
http://localhost:4200 server interface?
1. Hortonworks Sandbox downloads are available here: https://hortonworks.com/products/sandbox/
Additional details on Sandbox: https://hortonworks.com/tutorial/learning-the-ropes-of-the-hortonworks-sandbox/
2. The URL http://localhost:4200 provides SSH terminal access to the sandbox. So yes you can run the commands from the web terminal as well. But this web terminal is installed on HDP sandbox.
If you want to install web terminal on your own cluster then you will have to install the "" and then need to configure it
# yum install shellinabox
