  • conf-red-master.sh y conf-hadoop-master.sh (master): Copiar al directorio home de hduser

  • conf-red-slave.sh y conf-hadoop-slave.sh (slaves) : Copiar al directorio home de hduser segun corresponda el nodo(slave1,slave2,slave3)

Para cada nodo sin importar si es master o slave

sudo sh conf-general.sh
  • se obtiene: usuario: hduser contraseña: tux
$ su - hduser
$ ssh-keygen -t rsa -P ""

probar conexiones ssh para cada nodo
$ ssh hduser@slaveX (X={1,2,3})
REINICIAR master y slaves
