architecture

master / slave
- HMaster / Region servers
- However, client can go directly to the region server, not indirectly via the master.
Region?
- sharded table
HBase Java client API
- HBaseAdmin : communicate with the Master
- HTable : communicate with Region servers

Although the a concept of a Master exists, the HBase client does not depend on it for data operations and the cluster can keep serving data even if the master goes down.
