| Interface Summary | |
|---|---|
| CoprocessorProtocol | All custom RPC protocols to be exported by Coprocessors must extend this interface. |
| Delayable | A call whose response can be delayed by the server. |
| HBaseRPCErrorHandler | An interface for calling out of RPC for error conditions. |
| HMasterInterface | Clients interact with the HMasterInterface to gain access to meta-level HBase functionality, like finding an HRegionServer and creating/destroying tables. |
| HMasterRegionInterface | The Master publishes this Interface for RegionServers to register themselves on. |
| HRegionInterface | Clients interact with HRegionServers using a handle to the HRegionInterface. |
| RpcServer | |
| VersionedProtocol | Superclass of all protocols that use Hadoop RPC. |
| Class Summary | |
|---|---|
| ExecRPCInvoker | Backs a CoprocessorProtocol subclass proxy and forwards method
invocations for server execution. |
| HBaseClient | A client for an IPC service. |
| HBaseClient.ConnectionId | This class holds the address and the user ticket. |
| HBaseClient.ParallelResults | Result collector for parallel calls. |
| HBaseRPC | A simple RPC mechanism. |
| HBaseRpcMetrics | This class is for maintaining the various RPC statistics and publishing them through the metrics interfaces. |
| HBaseRPCStatistics | Exports HBase RPC statistics recorded in HBaseRpcMetrics as an MBean
for JMX monitoring. |
| HBaseServer | An abstract IPC service. |
| Invocation | A method invocation, including the method name and its parameters. |
| ProtocolSignature | |
| RequestContext | Represents client information (authenticated username, remote address, protocol) for the currently executing request within a RPC server handler thread. |
| Exception Summary | |
|---|---|
| HBaseRPC.UnknownProtocolException | An error requesting an RPC protocol that the server is not serving. |
| HBaseRPC.VersionMismatch | A version mismatch for the RPC protocol. |
| ServerNotRunningYetException | |
Tools to help define network clients and servers. This is the hadoop copied local so can fix bugs and make hbase-specific optimizations.
