现在效果很好我只将这些行留在我的hdfs-site.xml
<property>
<name>dfs.replication</name>
<value>2</value>
</property>
这会造成问题吗？
在我的集群的图形界面上，我只看到一个datanode 你可以看到她的enter image description here
数据节点信息偷偷摸摸你
答案 0 :(得分：0)
不推荐使用属性fs.default.name。请尝试下面的内容。
<property>
<name>fs.defaultFS</name>
<value>hdfs://NAME_NODE_HOST:8020</value>
</property>
查看日志后：
看起来你需要格式化namenode。
请尝试冰山的解决方案 Datanode not starts correctly
