Different ambari for new namepsace for different configurations for each service

Different ambari for new namepsace for different configurations for each service

New Contributor

Hi,

We have recently added a new namespace to existing hdp cluster using ambari. Since we have only one ambari we will have same configurations and properties for both the tenants or namespaces . Can we have different configurations and properties set at service level like hive for different namespaces ?

Can we have different ambari UI for each namespace so we can have the different configurations and properties ?

Ambari provides "Configuration Group" feature using which you can have different set of configurations for different hosts or group of hosts.

Ambari initially assigns all hosts in your cluster to one default configuration group for each service you install. For example, after deploying a three-node cluster with default configuration settings, each host belongs to one configuration group that has default configuration settings for the HDFS service.

Thanks @Jay for your suggestions.

can we have a different ambari UI for each namespace or Is it like same ambari for the all the namespaces we create ?

Is it possible to have different configurations at service level unlike host level. when hive is shared for multi tenants we have same metastore location that is one location for multiple namespaces. When we would like to have a different metastore for hive for new namespace , couldn't see any option for that.


Same case with hbase region servers and kafka brokers storage. Is it really possible to federate services like hive, hbase and kafka ? I have not tried with Spark yet. Any suggestions will be great.


Thanks,

Arshad
