我按照指令
here在伪分布式模式下安装hadoop.
但是,我无法连接到HDFS.
当我执行此命令时：
./hadoop fs -ls /
我得到的目录列表就像我应该的那样.
但是,当我执行此命令时：
./hadoop fs -ls hdfs://localhost/
我明白了：

如果我在这里浏览：
http://localhost:50070/dfshealth.jsp
我得到了NameNode系统健康页面,就像我应该的那样.但是,如果我按照“浏览文件系统”链接,我相信这里：
http://localhost:50070/nn_browsedfscontent.jsp
我从Jetty获得了404页面.
不知道这两件事是否相关,但这肯定会阻止我.我正在尝试按照here概述的伪分布式模式设置hbase,但我不能,因为hbase无法连接到端口8020上的hdfs.
信息
我在CENTOS 6.2上运行hadoop .20和hbase .90.6.
Hadoop和hbase从我编写的init.d脚本开始启动.
Hadoop在hadoop用户下运行,位于/ opt / hadoop中.在hadoop init.d脚本中,我使用daemon命令执行start-all.sh.
HBase在root下运行,位于/ opt / hbase中.在hbase init.d脚本中,我执行start-hbase.sh脚本.目前我在独立模式下运行HBase.
解决方法
看起来我错误地将fs.default.name设置为9000.将其更改为8020,现在一切正常.感谢mgorven的帮助！
