Hi @Dominik Ludwig

I haven't seen hard limits yet, how many clusters would you be trying to add? By the way, the feature is more about hosting Views for another cluster vs managing the operations of a remote cluster.

Hi @Sonu Sahi,

I want to manage about 20 Clusters on my "Super"-Ambari-Server. I Need the Feature for managing the Clusters. I have to create a System to inventory all Clusters in a Company. For example a Cluster has 4 Hosts and the next Cluster has 5 Hosts. I want see directly the Distribution of the Hosts on a Page. I have seen that you can use the Ambai-REST-API to get the relevant Information, but I am scare about the stability of the API. I don't want to change my program in the next release of Ambari only because Apache has changed the internal data model and the structure of the REST API.

It is possible to write own Ambari-Views or do you know another solution to cover the Use-Case? The official function of Ambari and their Views are not helpful.

Best Regards and Thanks

Dominik

Hi @Dominik Ludwig

I don't believe the current implementation of Ambari allows for it to manage multiple clusters yet.

The Ambari Views framework is an extensible framework, and does allow you to write your own View if you would like. You can find more details on the framework itself on the Apache website: https://cwiki.apache.org/confluence/display/AMBARI/Views including some examples of views implementations I believe.

Hi, that’s it. I write my own views and I extract the Apache-Ambari database to get the Data. I have seen that you can use Java for the views. In that case I want to use Hibernate for the connection to the database.

Many Thanks for your help
