A rough answer to this question (not necessarily comprehensive) 1. store root region's location 2. help select active master 3. help monitor regionservers' health 4. help table tasks such creating/deleting/enabling/disabling 5. help region-in-transition tasks such as assign/unassign/split/merge (store task status) 6. coordinate/dispatch hlog split tasks during regionserver failover 7. store replication configuration such as whether replication is enabled, peer configuration and setting, and etc 8. store cluster-id
