Package org.apache.accumulo.core.rpc

Class TTimeoutTransport

java.lang.Object

org.apache.accumulo.core.rpc.TTimeoutTransport

public class TTimeoutTransport
extends Object

A utility class for setting up a TTransport with various necessary configurations for ideal performance in Accumulo. These configurations include:

• Setting SO_LINGER=false on the socket.
• Setting TCP_NO_DELAY=true on the socket.
• Setting timeouts on the I/OStreams.

Method Detail

create

public static org.apache.thrift.transport.TTransport create(HostAndPort addr,
                                                            long timeoutMillis)
                                                     throws IOException

Creates a Thrift TTransport to the given address with the given timeout. All created resources are closed if an exception is thrown.

Parameters:

addr - The address to connect the client to

timeoutMillis - The timeout in milliseconds for the connection

Returns:

A TTransport connected to the given addr

Throws:

IOException - If the transport fails to be created/connected

create

public static org.apache.thrift.transport.TTransport create(SocketAddress addr,
                                                            long timeoutMillis)
                                                     throws IOException

Creates a Thrift TTransport to the given address with the given timeout. All created resources are closed if an exception is thrown.

Parameters:

addr - The address to connect the client to

timeoutMillis - The timeout in milliseconds for the connection

Returns:

A TTransport connected to the given addr

Throws:

IOException - If the transport fails to be created/connected

createInternal

protected org.apache.thrift.transport.TTransport createInternal(SocketAddress addr,
                                                                long timeoutMillis)
                                                         throws IOException

Opens a socket to the given addr, configures the socket, and then creates a Thrift transport using the socket.

Parameters:

addr - The address the socket should connect

timeoutMillis - The socket timeout in milliseconds

Returns:

A TTransport instance to the given addr

Throws:

IOException - If the Thrift client is failed to be connected/created

wrapInputStream

protected InputStream wrapInputStream(Socket socket,
                                      long timeoutMillis)
                               throws IOException

Throws:

IOException

wrapOutputStream

protected OutputStream wrapOutputStream(Socket socket,
                                        long timeoutMillis)
                                 throws IOException

Throws:

IOException

openSocket

protected Socket openSocket(SocketAddress addr)
                     throws IOException

Opens and configures a Socket for Accumulo RPC.

Parameters:

addr - The address to connect the socket to

Returns:

A socket connected to the given address, or null if the socket fails to connect

Throws:

IOException

openSocketChannel

protected Socket openSocketChannel()
                            throws IOException

Opens a socket channel and returns the underlying socket.

Throws:

IOException
