的bashrc

Question

我是hadoop，hdfs的新手。我已经做了下一步：

我已经在三个名字节点中启动了zookeeper：

*vagrant@172:~$ zkServer.sh start

我可以看到状态：

*vagrant@172:~$ zkServer.sh status

结果状态：

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

使用jps命令只显示jps，有时也会出现quaroom：

*vagrant@172:~$ jps
    2237 Jps

当我运行下一个命令时。

* vagrant@172:~$ hdfs zkfc -formatZK

对此错误的任何帮助对我都有很大的帮助。

我的配置是下一个：

的bashrc

JAVA_HOME=/usr/lib/jvm/java-8-oracle
export PATH=$PATH:$JAVA_HOME/bin

###HADOOP CONFIGURATION###

Answer 1

在文件hdfs-site.xml中：

*我已经更改了机器名称的所有IP。例： 172.16.8.191 - ＆gt; machine_Name1

然后在文件etc / hosts中：

*我已添加所有IP及其各自的名称

现在它运作得很好。

执行hdfs zkfc command

的bashrc

HDFS-site.xml中

芯-site.xml中

zoo.cfg
