使用jps命令时未列出Hadoop名称节点

-3

我是hadoop的新手。我通过以下链接安装了hadoop。 http://www.bogotobogo.com/Hadoop/BigData_hadoop_Install_on_ubuntu_single_node_cluster.php 使用jps命令时未列出Hadoop名称节点

所有安装完成后，执行start-all.sh命令。

服务器启动成功。但是，当输入jps命令时，它不会列出名称node.Output，如下所示。

6917 SecondaryNameNode 
7185 NodeManager 
6746 DataNode 
7060 ResourceManager 
7476 Jps

在hadoop-hduser-namenode-nag-VirtualBox.log日志文件显示休耕输出。

你能打开所有Hadoop的Web界面？ – 2015-02-06 10:31:14

''（权限被拒绝）' – 2015-02-06 10:40:35

是... SecondaryNameNode访问http：// localhost：50090/status.jsp – 2015-02-06 10:45:10

故障排除的第一步是重新启动守护程序。我建议你继续做下去，看看它是否正常。

sudo service hadoop-master stop 
sudo service hadoop-master start 
hadoop dfsadmin -safemode leave 
sudo jps

您应该给予启动用户权限。此外，它不支持三个或更多的名称节点。

因此，如果设置三个节点，Hadoop的-XXX-的NameNode，yyy.log想这样的：

java.lang.IllegalArgumentException: Expected exactly 2 NameNodes in namespace 'mycluster'. Instead, got only 3 (NN ids were 'nn1','nn2','nn3'

检查/usr/local/hadoop_store/hdfs/namenode/current/VERSION权限

使用jps命令时未列出Hadoop名称节点
