VirtualBox CentOS 6.4中的Accumulo初始化异常

时间：2014-08-20 21:52:52

标签： hadoop virtual-machine accumulo

我正在尝试启动Accumulo，我遇到了一个令人讨厌的异常，似乎与我的虚拟机的某些网络问题有关。我想到了命令

sudo -u accumulo /usr/lib/accumulo/bin/accumulo init --instance-name lumify --password password

会初始化accumulo。但是，我收到一个警告，表示已检测到地址更改，然后是致命异常。我注意到我没有在$ACCUMULO_HOME文件中定义accumulo-env.sh。我也注意到了唯一的＆＃34;大师＆＃34;和＆＃34;奴隶＆＃34;在主站和从站文件中只有一行表示localhost，而我的IP地址没有。我将localhost更改为这些文件中的IP地址，同样的问题仍然存在。

我很确定这是一个IP地址问题，但我严格按照说明操作。也许这是一个问题，因为我在虚拟机上（即使我使用桥接适配器并为我的虚拟机箱获得了真正的IP地址）？

我使用eth0检查我的ifconfig连接，但仍显示192.168.1.232，而我仍然收到消息

  

Hadoop Filesystem是hdfs：//192.168.1.232：8020

     

Accumulo数据目录是/ accumulo

     

Zookeeper服务器是localhost：2181

然后是警告

  

检测到地址变化。旧：localhost.localdomain / 192.168.1.232:8020新：localhost.localdomain / 127.0.0.1:8020

和例外

  

无法检查文件系统是否已初始化。

似乎即使没有不同的网络，我的VM也是我运行设置时的IP地址，我在初始化accumulo的过程中得到了这块砖。

有什么建议吗？堆栈跟踪以

继续
  

ConnectException：从localhost.localdomain / 127.0.0.1调用localhost.localdomain：8020连接异常失败：连接被拒绝

如果它有帮助，这里是堆栈跟踪：

Warning!!! Your instance secret is still set to the default, this is not secure. We highly recommend you change it.


You can change the instance secret in accumulo by using:
   bin/accumulo org.apache.accumulo.server.util.ChangeSecret oldPassword newPassword.
You will also need to edit your secret in your configuration file by adding the property instance.secret to your conf/accumulo-site.xml. Without this accumulo will not operate correctly

您应该验证您的DNS和/etc/hosts设置是否配置正确，并与masters和slaves文件保持一致。
