We have enabled HDFS Federation and want to have seperate namespaces - one for each department (I know we are almost trying to setup a functional multi-tenant env).
We also want to have a seperate Hive server - one for each department and talking to respective namenode.
How can we achieve this?
- One metastore per department having rootFS configured?
- Would it be possible to have two different Hive services in one cluster, working independently with namenodes/nameservices associated with each of the department?
