Buenas, me está dando error al conectarme al spark-shell, un error al parecer de IP. He intentado modificar el fichero spark-env.sh poniendo :

SPARK_LOCAL_IP="<IP address>"

Pero no me deja modificar el fichero porque me dice que no tengo permisos.

Este es el log de error que me sale:

19/01/23 10:28:39 WARN util.Utils: Your hostname, quickstart.cloudera resolves to a loopback address: 127.0.0.1; using 192.168.149.128 instead (on interface eth1)
