启动Hadoop时遇到Name or service not knownstname 错误

时间:2016-11-01  来源:未知  作者:linuxsir首页

今天在启动Hadoop时遇到Name or service not knownstname这样的错误

1 : Name or service not knownstname master 
2 : Name or service not knownstname slaver1 
3 : Name or service not knownstname slaver2

原因:slaves文件可能被污染了。

解决方法:删除掉slaves文件,重新建立一个slaves文件,并配置好就可以了。

[root@master sbin]# ./start-all.sh
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
