apache - 名称节点未启动

Question

我正在尝试设置一个 hadoop 集群。但是名称节点没有启动。当我检查日志时，它显示:

2016-10-19 05:23:10,140 FATAL org.apache.hadoop.hdfs.server.namenode.

SHUTDOWN_MSG:

/************************************************************

SHUTDOWN_MSG: Shutting down NameNode at namenode1/192.168.100.101

我检查了 core-site.xml 文件，没有发现任何错误。

<configuration>

<property>
<name>fs.default.name</name>
<value>192.168.100.101:9001</value>
</property>
</configuration>
~                  

我也试过删除临时文件夹，格式化名称节点并重新启动它。

Answer 1

1) 将 fs.default.name 的值替换为 hdfs://192.168.100.101:9001

2) 检查你的 site.xml 文件，是否在值之间错误地添加了空格
