List of coprocessorService() Examples

Examples of coprocessorService()

org.apache.hadoop.hbase.client.Admin.coprocessorService()
Creates and returns a {@link com.google.protobuf.RpcChannel} instance connected to the activemaster.
The obtained {@link com.google.protobuf.RpcChannel} instance can be used to accessa published coprocessor {@link com.google.protobuf.Service} using standard protobuf serviceinvocations:
```
 CoprocessorRpcChannel channel = myAdmin.coprocessorService(); MyService.BlockingInterface service = MyService.newBlockingStub(channel); MyCallRequest request = MyCallRequest.newBuilder() ... .build(); MyCallResponse response = service.myCall(null, request); 
```
@return A MasterCoprocessorRpcChannel instance
org.apache.hadoop.hbase.client.HBaseAdmin.coprocessorService()
Creates and returns a {@link com.google.protobuf.RpcChannel} instanceconnected to the active master.
The obtained {@link com.google.protobuf.RpcChannel} instance can be used to access a publishedcoprocessor {@link com.google.protobuf.Service} using standard protobuf service invocations:
```
 CoprocessorRpcChannel channel = myAdmin.coprocessorService(); MyService.BlockingInterface service = MyService.newBlockingStub(channel); MyCallRequest request = MyCallRequest.newBuilder() ... .build(); MyCallResponse response = service.myCall(null, request); 
```
@return A MasterCoprocessorRpcChannel instance
org.apache.hadoop.hbase.client.HTable.coprocessorService()
{@inheritDoc}
org.apache.hadoop.hbase.client.HTableInterface.coprocessorService()
Creates and returns a {@link com.google.protobuf.RpcChannel} instance connected to thetable region containing the specified row. The row given does not actually have to exist. Whichever region would contain the row based on start and end keys will be used. Note that the {@code row} parameter is also not passed to thecoprocessor handler registered for this protocol, unless the {@code row}is separately passed as an argument in the service request. The parameter here is only used to locate the region used to handle the call.
The obtained {@link com.google.protobuf.RpcChannel} instance can be used to access a publishedcoprocessor {@link com.google.protobuf.Service} using standard protobuf service invocations:
```
 CoprocessorRpcChannel channel = myTable.coprocessorService(rowkey); MyService.BlockingInterface service = MyService.newBlockingStub(channel); MyCallRequest request = MyCallRequest.newBuilder() ... .build(); MyCallResponse response = service.myCall(null, request); 
```
@param row The row key used to identify the remote region location @return A CoprocessorRpcChannel instance
org.apache.hadoop.hbase.client.Table.coprocessorService()
