我正在尝试在非 Cloudera Ubuntu 测试映像上安装 Hadoop。在我跑步之前，一切似乎都很顺利./bin/start-all.sh。名称节点永远不会出现，所以我什至无法运行 ahadoop fs -ls来连接到文件系统。

这是名称节点日志：

2011-03-24 11:38:00,256 INFO org.apache.hadoop.ipc.Server: Stopping server on 54310
2011-03-24 11:38:00,257 ERROR org.apache.hadoop.hdfs.server.namenode.NameNode: org.apache.hadoop.hdfs.server.common.InconsistentFSStateException: Directory /usr/local/hadoop-datastore/hadoop-hadoop/dfs/name is in an inconsistent state: storage directory does not exist or is not accessible.

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

我已经chmod -R 755在根目录上，甚至通过使用mkdir -p.

hadoop@Brash:/usr/lib/hadoop$ ls -la /usr/local/hadoop-datastore/hadoop-hadoop/dfs/
total 16
drwxr-xr-x 4 hadoop hadoop 4096 2011-03-24 11:41 .
drwxr-xr-x 4 hadoop hadoop 4096 2011-03-24 11:31 ..
drwxr-xr-x 2 hadoop hadoop 4096 2011-03-24 11:31 data
drwxr-xr-x 2 hadoop hadoop 4096 2011-03-24 11:41 name

这是我的/conf/hdfs-site.xml：

hadoop@Brash:/usr/lib/hadoop$ cat conf/hdfs-site.xml
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
  <name>dfs.replication</name>
  <value>1</value>
  <description>Default block replication.
  The actual number of replications can be specified when the file is created.
  The default is used if replication is not specified in create time.
  </description>
</property>
</configuration>

您永远不必自己创建目录。它会自行创建。你忘记格式化namenode了吗？删除现有目录，然后重新格式化 namenode ( bin/hadoop namenode -format) 并重试。
