Spark集群修改ip后一直去连老的Master是怎么回事？

Spark集群迁移了，ip地址发生了改变，我修改了conf下的hdfs-site.xml,slaves,spark-defaults.conf,spark-env.sh四个配置文件和hadoopconf下的hffs-site.xmlhe yarn-site.xml两个配置文件。重启后用jps -m查看有这些进程：

187466 Worker --webui-port 18081 spark://spark-11.server:7077

179369 Worker --webui-port 18083 spark://spark-11.server:7077

174577 Jps -m

172118 Worker --webui-port 18082 spark://spark-11.server:7077

170921 Worker --webui-port 18084 spark://spark-11.server:7077

177586 Master --ip spark-11.server --port 7077 --webui-port 18080

但是过一段时间进程就没了。

查看日志发现报错：

Spark-11还是没改之前的master，是什么原因导致修改的没生效呢，spark-defaults.conf里面的spark.master我已经修改成新的hostname了，有没有大神帮忙看看？？？
