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

org.apache.hadoop.hbase.ipc.RegionCoprocessorRpcChannel
Provides clients with an RPC connection to call coprocessor endpoint {@link com.google.protobuf.Service}s against a given table region. An instance of this class may be obtained by calling {@link org.apache.hadoop.hbase.client.HTable#coprocessorService(byte[])}, but should normally only be used in creating a new {@link com.google.protobuf.Service} stub to call the endpointmethods. @see org.apache.hadoop.hbase.client.HTable#coprocessorService(byte[])
