本文介绍了执行 hdfs zkfc 命令时出错的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我是 hadoop、hdfs 的新手.我已经完成了接下来的步骤:

我已经在三个namenodes中启动了zookeeper:

*vagrant@172:~$ zkServer.sh start

我可以看到状态:

*vagrant@172:~$ zkServer.sh 状态

结果状态:

默认启用JMX使用配置:/opt/zookeeper-3.4.6/bin/../conf/zoo.cfg模式:跟随

使用 jps 命令只会出现 jps，有时也会出现 quaroom:

*vagrant@172:~$ jps2237 日元

当我运行下一个命令时.

* vagrant@172:~$ hdfs zkfc -formatZK16/01/07 16:10:09 INFO zookeeper.ClientCnxn:打开与服务器 172.16.8.192/172.16.8.192:2181 的套接字连接.不会尝试使用 SASL 进行身份验证(未知错误)16/01/07 16:10:10 INFO zookeeper.ClientCnxn:建立到 172.16.8.192/172.16.8.192:2181 的套接字连接，发起会话16/01/07 16:10:11 INFO zookeeper.ClientCnxn:在服务器 172.16.8.192/172.16.8.192:2181 上完成会话建立，sessionid = 0x2521cd93c970022，协商超时 = 6000用法:java zkfc [ -formatZK [-force] [-nonInteractive] ]16/01/07 16:10:11 信息 ha.ActiveStandbyElector:会话已连接.16/01/07 16:10:11 INFO zookeeper.ZooKeeper:会话:0x2521cd93c970022 关闭16/01/07 16:10:11 信息 zookeeper.ClientCnxn:EventThread 关闭16/01/07 16:10:12 FATAL tools.DFSZKFailoverController:遇到致命错误，现在退出org.apache.hadoop.HadoopIllegalArgumentException:错误的参数:–formatZK在 org.apache.hadoop.ha.ZKFailoverController.badArg(ZKFailoverController.java:251)在 org.apache.hadoop.ha.ZKFailoverController.doRun(ZKFailoverController.java:214)在 org.apache.hadoop.ha.ZKFailoverController.access$000(ZKFailoverController.java:61)在 org.apache.hadoop.ha.ZKFailoverController$1.run(ZKFailoverController.java:172)在 org.apache.hadoop.ha.ZKFailoverController$1.run(ZKFailoverController.java:168)在 org.apache.hadoop.security.SecurityUtil.doAsLoginUserOrFatal(SecurityUtil.java:415)在 org.apache.hadoop.ha.ZKFailoverController.run(ZKFailoverController.java:168)在 org.apache.hadoop.hdfs.tools.DFSZKFailoverController.main(DFSZKFailoverController.java:181)

对这个错误的任何帮助对我来说都是一个很大的帮助.

我的配置如下:

bashrc

###JAVA 配置###JAVA_HOME=/usr/lib/jvm/java-8-oracle导出路径=$PATH:$JAVA_HOME/bin###HADOOP 配置###HADOOP_PREFIX=/opt/hadoop-2.7.1/导出路径=$PATH:$HADOOP_PREFIX/bin:$HADOOP_PREFIX/sbin###动物园管理员###导出路径=$PATH:/opt/zookeeper-3.4.6/bin

zoo.cfg

 tickTime=2000dataDir=/opt/ZooData客户端端口=2181初始限制=5同步限制=2server.1=172.16.8.191:2888:3888server.2=172.16.8.192:2888:3888server.3=172.16.8.193:2888:3888

解决方案

在文件 hdfs-site.xml 中:

*我已经更改了机器名称的所有 IP.例子:172.16.8.191 --> machine_Name1

然后在文件 etc/hosts 中:

*我已经添加了所有具有各自名称的 IP

现在它工作得很好.

I am new to hadoop, hdfs.. I have do the next steps:

I have started zookeeper in the three namenodes:

*vagrant@172:~$ zkServer.sh start

I can see the status:

*vagrant@172:~$ zkServer.sh status

Result Status:

JMX enabled by default
    Using config: /opt/zookeeper-3.4.6/bin/../conf/zoo.cfg
    Mode: follower

with jps command only appear jps and sometimes appear quaroom too:

*vagrant@172:~$ jps
    2237 Jps

When I run the next command.

* vagrant@172:~$ hdfs zkfc -formatZK

Any help for this error would be a great help for me.

 tickTime=2000

        dataDir=/opt/ZooData

        clientPort=2181

        initLimit=5
        syncLimit=2
        server.1=172.16.8.191:2888:3888
        server.2=172.16.8.192:2888:3888
        server.3=172.16.8.193:2888:3888

解决方案

In file hdfs-site.xml:

*I have change all the IPs for the name of the machine. Example: 172.16.8.191 --> machine_Name1

Then in file etc/hosts:

*I have add all the IPs with their respective names

And now it is working perfectly.
