我正在使用hadoop，它工作正常。但今天当我重新启动服务器时，现在jps命令显示的内容类似于
9801 NameNode
12142 Jps
10207 SecondaryNameNode
我已经从http://pingax.com/install-hadoop2-6-0-on-ubuntu/
重新配置了文件注意： - 重新启动后，服务器名称已从
更改hduser@hadoop-master:
到
hduser@silp-ProLiant-DL360-Gen9:
是否因服务器名称或其他问题而出现问题？
在start-all.sh命令之后显示
hduser@silp-ProLiant-DL360-Gen9:~$ start-all.sh
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh

请帮忙
