我正在尝试使用 3 台名称节点机器、2 台数据节点机器和 1 台客户端机器运行 hdfs。

当我执行 hdfs zkfc –formatZK 我有下一个 fatal error ，我不知道为什么，因为我已经尝试过其他几次集群并且它有效，但现在它不起作用。

16/01/21 15:05:14 INFO zookeeper.ZooKeeper: Session: 0x25264b6c3d90000 closed

我可以毫无错误地运行下一个命令:

namenode1$ `hadoop-daemon.sh start journalnode`
namenode2$ `hadoop-daemon.sh start journalnode`
namenode3$ `hadoop-daemon.sh start journalnode`

namenode1$ `hadoop namenode -format`
namenode1$ `hadoop-daemon.sh start namenode`

namenode2$ `hadoop namenode -bootstrapStandby`
namenode2$ `hadoop-daemon.sh start namenode`

namenode1$ `hadoop-daemon.sh start zkfc`
namenode2$ `hadoop-daemon.sh start zkfc`
namenode3$ `hadoop-daemon.sh start zkfc`

但是当我使用 namenode1:50070 访问网页时，它看起来像待机，而 namenode2:50070 到。 我尝试将 hdfs haadmin -getServiceState nn01 与 nn01 和 nn02 一起使用，但两者都显示为待机状态。

接下来是我的配置:

最佳答案

当我从 microsoft-word 复制命令“hdfs zkfc –formatZK”时，该行比您必须在终端中输入的命令的实际行长。

Word command: hdfs zkfc –formatZK

Real command: hdfs zkfc -formatZK

关于javascript - 执行hdfs zkfc命令时出错，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34000403/
