我用的是hadoop，效果很好。但是今天当我重新启动服务器时，现在jps命令显示

9801 NameNode
12142 Jps
10207 SecondaryNameNode

我重新配置了文件http://pingax.com/install-hadoop2-6-0-on-ubuntu/
注意：-重新启动后，服务器名称已从更改为

hduser@hadoop-master:

到

hduser@silp-ProLiant-DL360-Gen9:

由于服务器名或其他原因是否有任何问题？
显示start-all.sh命令后

hduser@silp-ProLiant-DL360-Gen9:~$ start-all.sh
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
