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

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

将初始化accumulo。但是，我得到一个警告，说检测到地址更改，然后是一个致命的异常。我注意到我没有 $ACCUMULO_HOME 定义在 accumulo-env.sh 文件。我还注意到，在masters和slaves文件中，只有一行“masters”和“slaves”表示 localhost ，没有我的ip地址。我变了 localhost 我的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，但我严格按照说明进行了操作。也许这是一个问题，因为我在一个虚拟机上（即使我正在使用桥接适配器并为我的虚拟机获得一个真实的ip地址）？
我检查我的房间 eth0 连接使用 ifconfig 它仍然显示 192.168.1.232 ，而我仍然收到消息
hadoop文件系统是hdfs://192.168.1.232:8020
accumulo数据目录is/accumulo
zookeeper服务器是localhost:2181
然后是警告
检测到地址更改。旧的：localhost.localdomain/192.168.1.232:8020新的：localhost.localdomain/127.0.0.1:8020
例外情况呢
无法检查文件系统是否已初始化。
看起来，即使没有不同的网络，我的虚拟机的ip地址与我运行安装程序时的相同，我在初始化accumulo的过程中得到了这个砖块。
有什么建议吗？堆栈跟踪以
connectexception:从localhost.localdomain/127.0.0.1调用localhost.localdomain:8020 failed 连接异常：连接被拒绝
下面是堆栈跟踪，如果有帮助的话：

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
