Hive/hbase multi tenant environment

Hive/hbase multi tenant environment

We have added a new namespace to our existing one namespace cluster.

We have services like hive/spark/hbase/Kafka/ which are using default namespace for storage and processing.

We would like to have different hive metastore for our new namespace. Is it possible to have different hive metastore for different namespaces ?

I see that we can give new namespace as a location when you are creating hive tables but does any one implemented federation/ multi tenant for hbase?

I think federation is not applicable for Kafka as it stores the streams in the host where Kafka brokers are running not in hdfs.

I really appreciate if some one can guide me with the above questions.
