hadoop - 名称节点和辅助名称节点未启动

Question

我是Hadoop世界的新手，我正在尝试从tutorial学习基础知识。我已经以伪分布式方式在机器上全新安装了Hadoop 2.9.2，并进行了以下设置。

core-site.xml

<configuration>
  <propeerty>
    <name>fs.defaultFS</name>
    <value>hdfs://localhost:9000</value>
  </propeerty>
</configuration>

hdfs-site.xml

<configuration>
  <property>
    <name>dfs.replication</name>
    <value>1</value>
  </property>
</configuration>

mapred-site.xml

<configuration>
  <property>
    <name>mapreduce.framework.name</name>
    <value>yarn</value>
  </property>
</configuration>

yarn-site.xml

<configuration>
  <property>
    <name>yarn.nodemanager.aux-services</name>
    <value>mapreduce_shuffle</value>
  </property>
</configuration>

跑oji​​t_code顺利进行，没有任何错误，然后最终跑 bin/hdfs namenode -format，在以下日志中我没有任何错误

当我转到 sbin/start-dfs.sh时，我什么也没收到(无法访问站点)，当我按下 localhost:50070时，我看不到任何namenode或secondary namenode在运行。

我做了什么？

引用Incorrect configuration: namenode address dfs.namenode.rpc-address is not configured并确保任何配置中都没有空格(已在描述中列出)

是否需要配置某些内容或我缺少的任何内容？

提前致谢!

Answer 1

core-site.xml属性标签有错字!它必须是property而不是propeerty。

<configuration>
  <property>
    <name>fs.defaultFS</name>
    <value>hdfs://localhost:9000</value>
  </property>
</configuration>

另外，在 hdfs-site.xml中，您没有提到 dfs.namenode.name.dir和 dfs.datanode.data.dir属性。始终建议配置这些属性，否则建议将 hadoop.tmp.dir属性(在 core-site.xml中)配置为 /tmp以外的某个目录。

更新这些属性，格式化namenode并启动服务。
