@Mas_Jamie CDS table is for Column Descriptors. CD stands for column descriptor. It is used to decouple columns from tables/partitions to reduce storage needs. tables/partitions are almost 1-1 map to these descriptors… but a table may have more than one Column Descriptor in the case of schema evolution!

Lets take an example Hiveserver1 ==> HMS ==> Mysqldatabase with schema(hive) ==> Contains databases as students(student database is in hive not MySQL) Hiveserver2 ==> HMS ==> Mysqldatabase with schema(test) ==> Contains databases as employee(employee database is in hive not MySQL)] When connected to beeline ==> hiveserve1 ==> Show databases would yield students When connected to beeline ==> hiveserve2 ==> Show databases would yield employees This must be performed using config groups in ambari. In CM it must be used using role instances.

@mailsmail This is not tested yet. You can create a POC environment and test. I don't have to create/run new MySQL instance for each metastore. Ans: A separatevschema is required. Avoid using hive/metastore as this would be by-default. use a different database/schema. Is it possible for one hiveserver2 to connect to multiple metastore, so all user will use the same endpoint? or do I have to run another hiveserver2 for each metastore? Ans: You can have one hiveserver2 to connect to multiple HMS by updating "hive.metastore.uris" field. You need to create a separate config group for another HMS with different database and also you need a different hiveserver2 and update "hive.metastore.uris" accordingly Please let me know,if you have any queries or accept it as solution,if your queries are answered.

@mailsmail You can have below approach: 1. create a separate schema in metastore db named user2 2. Add a hivemetastore pointing to same MySQL but different db user2 on hostA 3. Add a separate hiveserver2 on hostA 4. Create a config group and add the hostA 5. Override metastore uri for hiveserver2 This is one way you can achieve multitenancy.Your databases in hive would remain independent. Please let us know if you have additional quries.
