我的namenode没有启动。
在尝试重新启动之前尝试格式化并删除tmp目录。但它没有出现。
目前我正在寻找一个双节点集群。我从单个节点机器克隆了两个节点。并且将属性更改为类似于名称节点，作业跟踪器和辅助名称节点的属性。剩下的就是另一个。
尝试启动名称节点时。我在日志中遇到异常。尝试搜索，但没有发现任何特定于我的问题。此外，我已设置密码少ssh，以防任何权限被拒绝，因为这。

我认为您没有正确授予namenode元数据位置的权限。为确保其正常工作，请按照以下步骤验证您的步骤。
假设Namenode元数据位置：/storage/name
mkdir -p /storage/name chown -R hdfs:hadoop /storage/name sudo -u hdfs hadoop namenode -format service hdfs-namenode start（假设使用了cdh rpm安装。这会因您使用的安装方法而异） Hadoop守护程序将以hdfs用户身份启动，如果元数据位置权限未设置为hadoop user和hadoop超级用户组，则会出现上述错误。
如果您观察到上面生成的日志，则FileSystem所有者：fsOwner为hdfs，超级组为supergroup。而且异常是FileNotFound，因为负责启动namenode的服务无法访问文件系统，因为它没有所需的权限。

在向hdfs添加另一个磁盘后，我在hortonworks中遇到了相同的问题。我只是做了chown hdfs:hadoop -R /hadoop/hdfs，它开始起作用。
