Hadoop v2.7伪分布式安装NativeCodeLoader报错

Question

我尝试在我的系统中安装 hadoop，首先我获得了权限，我可以通过一个简单的 chmod 和 chown 解决这个问题，但是在解决这个问题之后，现在每当我使用时都会出现一个新的错误start-dfs.sh

kishan@RoCk ~ $ start-dfs.sh
17/04/08 12:22:18 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable 
Incorrect configuration: namenode address dfs.namenode.servicerpc-address or dfs.namenode.rpc-address is not configured.

这是一个警告，但所有节点都不是运行。

Answer 1

org.apache.hadoop.hdfs.server.common.InconsistentFSStateException: Directory /home/kishan/hdfs/namenode is in an inconsistent state: storage directory does not exist or is not accessible

您的 Namenode 需要格式。

hdfs namenode -format

如果 Datanode 数据目录已经创建，请在重新启动集群之前手动删除它们。
