Class UGIAssumingTransport

java.lang.Object

org.apache.thrift.transport.TTransport

org.apache.accumulo.core.rpc.FilterTransport

org.apache.accumulo.core.rpc.UGIAssumingTransport

All Implemented Interfaces:

Closeable, AutoCloseable

public class UGIAssumingTransport
extends FilterTransport

The Thrift SASL transports call Sasl.createSaslServer and Sasl.createSaslClient inside open(). So, we need to assume the correct UGI when the transport is opened so that the SASL mechanisms have access to the right principal. This transport wraps the Sasl transports to set up the right UGI context for open(). This is used on the client side, where the API explicitly opens a transport to the server.
