Examples of org.apache.hadoop.hbase.ipc.HMasterInterface

org.apache.hadoop.hbase.ipc.HMasterInterface
Clients interact with the HMasterInterface to gain access to meta-level HBase functionality, like finding an HRegionServer and creating/destroying tables.
NOTE: if you change the interface, you must change the RPC version number in HBaseRPCProtocolVersion
