Eu configurei um ambiente de teste de carga distribuída usando o JMeter. estou usandoTrês máquinas Linux (RedHat) (IPs:xxx.xxx.xxx.121,xxx.xxx.xxx.122,xxx.xxx.xxx.123) usando o Shell Seguro do meu Windows 8.1.

Eu cumpri o pré-requisito para executar o teste distribuído:

Todas as máquinas (clientes e escravos) estão na mesma sub-rede.O firewall está desativado para todas as máquinas.O JMeter (2.13) e a versão do JDk (1.6.0_25) são iguais para todos.

Client(Master) Machine :xxx.xxx.xxx.123 Server(Slave) Machines: xxx.xxx.xxx.122,xxx.xxx.xxx.121

Eu fiz o seguinte:

1) Adicionado o seguinte ao cliente (mestre)jmeter.properties Arquivo:

remote_hosts= xxx.xxx.xxx.122,xxx.xxx.xxx.121

2) Adicionado o seguinte aos servidores (em cada máquina escrava)jmeter-server:

RMI_HOST_DEF=-Djava.rmi.server.hostname=xxx.xxx.xxx.123(IP da máquina cliente)

3) Então começoujmeter-server dessas duas máquinas escravas (xxx.xxx.xxx.122, xxx.xxx.xxx.121) usando este comando

./jmeter-server

e seguirresultado.O que significa que as máquinas escravas são iniciadas.

Saída de xxx.xxx.xxx.121:

Created remote object: UnicastServerRef [liveRef: [endpoint:[xxx.xxx.xxx.123:41864](local),objID:[1707296d:154c281318b:-7fff, -8101068266055605468]]]

Saída de xxx.xxx.xxx.122:

Using local port: 4000
Created remote object: UnicastServerRef [liveRef: [endpoint:[xxx.xxx.xxx.123:4000](local),objID:[-2a2acf13:154c285ffa2:-7fff, 2939294752655639469]]]

Agora eu executei o seguinte comando demáquina cliente(xxx.xxx.xxx.123) para iniciartestes remotos.

./jmeter -n -t RemoteTest.jmx -r

Ele me forneceu a seguinte saída:

Então, qual poderia ser a solução exata para superar essa exceção? Passei os últimos dois dias explorandoStackOverflow eTroca de pilha para perguntas semelhantes e já tentei quase todas as soluções possíveis, mas ainda não consigo me livrar dessa exceção. Na verdade, eu falhei !!!!Portanto, seja específico e detalhe suas respostas.
