• Class Summary 

  Class	Description
  AbstractRpcClient<T extends org.apache.hadoop.hbase.ipc.RpcConnection>	Provides the basics for a RpcClient implementation like configuration and Logging.
  AbstractRpcClient.BlockingRpcChannelImplementation	Blocking rpc channel that goes via hbase rpc.
  AbstractRpcClient.RpcChannelImplementation	Async rpc channel that goes via hbase rpc.
  AdaptiveLifoCoDelCallQueue	Adaptive LIFO blocking queue utilizing CoDel algorithm to prevent queue overloading.
  BalancedQueueRpcExecutor	An RpcExecutor that will balance requests evenly across all its queues, but still remains efficient with a single queue via an inlinable queue balancing mechanism.
  BlockingRpcCallback<R>	Simple RpcCallback implementation providing a Future-like BlockingRpcCallback.get() method, which will block util the instance's BlockingRpcCallback.run(Object) method has been called.
  BlockingRpcClient	Does RPC against a cluster.
  CallRunner	The request processing logic, which is usually executed in thread pools provided by an RpcScheduler.
  ConnectionId	This class holds the address and the user ticket, etc.
  CoprocessorRpcChannel	Base class which provides clients with an RPC connection to call coprocessor endpoint Services.
  CoprocessorRpcUtils	Utilities for handling coprocessor service calls.
  DelegatingHBaseRpcController	Simple delegating controller for use with the RpcControllerFactory to help override standard behavior of a HBaseRpcController.
  FailedServers	A class to manage a list of servers that failed recently.
  FastPathBalancedQueueRpcExecutor	Balanced queue executor with a fastpath.
  FifoRpcScheduler	A very simple RpcScheduler} that serves incoming requests in order.
  HBaseRpcControllerImpl	Optionally carries Cells across the proxy/service interface down into ipc.
  MasterCoprocessorRpcChannel	Provides clients with an RPC connection to call coprocessor endpoint Services against the active master.
  MetricsHBaseServer
  MetricsHBaseServerSourceFactory
  MetricsHBaseServerSourceFactoryImpl
  MetricsHBaseServerSourceImpl
  MetricsHBaseServerWrapperImpl
  NettyRpcClient	Netty client for the requests and responses.
  NettyRpcClientConfigHelper	Helper class for passing config to NettyRpcClient.
  RegionCoprocessorRpcChannel	Provides clients with an RPC connection to call coprocessor endpoint Services against a given table region.
  RegionServerCoprocessorRpcChannel	Provides clients with an RPC connection to call coprocessor endpoint Services against a given region server.
  RpcClientFactory	Factory to create a RpcClient
  RpcControllerFactory	Factory to create a HBaseRpcController.
  RpcExecutor	Runs the CallRunners passed here via RpcExecutor.dispatch(CallRunner).
  RpcExecutor.QueueBalancer
  RpcScheduler	An interface for RPC request scheduling algorithm.
  RpcScheduler.Context	Exposes runtime information of a RpcServer that a RpcScheduler may need.
  RpcServer	An RPC server that hosts protobuf described Services.
  RpcServer.BlockingServiceAndInterface	Datastructure for passing a BlockingService and its associated class of protobuf service interface.
  RWQueueRpcExecutor	RPC Executor that uses different queues for reads and writes.
  ServerRpcController	Used for server-side protobuf RPC service invocations.
  SimpleRpcScheduler	The default scheduler.

• Exception Summary 

  Exception	Description
  BadAuthException
  CallCancelledException	Client side call cancelled.
  CallerDisconnectedException	Exception indicating that the remote host making this IPC lost its IPC connection.
  CallTimeoutException	Client-side call timeout
  CellScannerButNoCodecException	Thrown if a cellscanner but no codec to encode it with.
  EmptyServiceNameException
  FailedServerException	Indicates that we're trying to connect to a already known as dead server.
  FallbackDisallowedException	Indicate that the rpc server tells client to fallback to simple auth but client is disabled to do so.
  FatalConnectionException	Thrown when server finds fatal issue w/ connection setup: e.g.
  RemoteWithExtrasException	A RemoteException with some extra information.
  ServerNotRunningYetException

• Annotation Types Summary 

  Annotation Type	Description
  QosPriority	Annotation which decorates RPC methods to denote the relative priority among other RPCs in the same server.
