Method Detail

getServerTransportFactory

public static org.apache.thrift.transport.TTransportFactory getServerTransportFactory(TachyonConf tachyonConf)
                                                                               throws SaslException

For server side, this method returns a TTransportFactory based on the auth type. It is used as one argument to build a Thrift TServer. If the auth type is not supported or recognized, an UnsupportedOperationException is thrown.

Parameters:

tachyonConf - Tachyon Configuration

Returns:

a corresponding TTransportFactory

Throws:

SaslException - if building a TransportFactory fails

getClientTransport

public static org.apache.thrift.transport.TTransport getClientTransport(TachyonConf tachyonConf,
                                                        InetSocketAddress serverAddress)
                                                                 throws IOException

Creates a transport per the connection options. Supported transport options are: NOSASL, SIMPLE, CUSTOM, KERBEROS. With NOSASL as input, an unmodified TTransport is returned; with SIMPLE/CUSTOM as input, a PlainClientTransport is returned; KERBEROS is not supported currently. If the auth type is not supported or recognized, an UnsupportedOperationException is thrown.

Parameters:

tachyonConf - Tachyon Configuration

serverAddress - the server address which clients will connect to

Returns:

a TTransport for client

Throws:

IOException - if building a TransportFactory fails or user login fails

createTSocket

public static org.apache.thrift.transport.TSocket createTSocket(InetSocketAddress address)

Creates a new Thrift socket what will connect to the given address

Parameters:

address - The given address to connect

Returns:

An unconnected socket
