• Class Summary 

  Class	Description
  AbstractRpcClient	Provides the basics for a RpcClient implementation like configuration and Logging.
  AbstractRpcClient.BlockingRpcChannelImplementation	Blocking rpc channel that goes via hbase rpc.
  AsyncCall	Represents an Async Hbase call and its response.
  AsyncRpcChannel	Netty RPC channel
  AsyncRpcChannel.CallWriteListener	Listens to call writes and fails if write failed
  AsyncRpcClient	Netty client for the requests and responses
  AsyncRpcClient.RpcChannelImplementation	Blocking rpc channel that goes via hbase rpc.
  AsyncServerResponseHandler	Handles Hbase responses
  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.
  BufferChain	Chain of ByteBuffers.
  Call	A call waiting for a value.
  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.
  DelegatingPayloadCarryingRpcController	Simple delegating controller for use with the RpcControllerFactory to help override standard behavior of a PayloadCarryingRpcController.
  FailedServers	A class to manage a list of servers that failed recently.
  FifoRpcScheduler	A very simple RpcScheduler} that serves incoming requests in order.
  IPCUtil	Utility to help ipc'ing.
  MasterCoprocessorRpcChannel	Provides clients with an RPC connection to call coprocessor endpoint Services against the active master.
  MetricsHBaseServer
  MetricsHBaseServerSourceFactory
  MetricsHBaseServerSourceFactoryImpl
  MetricsHBaseServerSourceImpl
  MetricsHBaseServerWrapperImpl
  PayloadCarryingRpcController	Optionally carries Cells across the proxy/service interface down into ipc.
  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
  RpcClientImpl	Does RPC against a cluster.
  RpcClientImpl.CallFuture	see RpcClientImpl.Connection.CallSender
  RpcControllerFactory	Factory to create a PayloadCarryingRpcController
  RpcExecutor
  RpcExecutor.QueueBalancer
  RpcExecutor.RandomQueueBalancer	Queue balancer that just randomly selects a queue in the range [0, num queues).
  RpcScheduler	An interface for RPC request scheduling algorithm.
  RpcScheduler.Context	Exposes runtime information of a RpcServer that a RpcScheduler may need.
  RpcSchedulerContext
  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	A scheduler that maintains isolated handler pools for general, high-priority, and replication requests.
  SimpleRpcScheduler.CallPriorityComparator	Comparator used by the "normal callQueue" if DEADLINE_CALL_QUEUE_CONF_KEY is set to true.
  TimeLimitedRpcController
