我按照有关voltdb的官方文档，但在使用
时遇到错误voltdb init --config=deployment.xml
init voltdb配置文件。 错误是
ERROR: Deployment information could not be obtained from cluster node or locally
VoltDB has encountered an unrecoverable error and is exiting
The log may contain additional information.
我的voltdb版本是 voltdb-community-8.0

因此，它导致无法生成配置文件。请告诉我有关＆＃34;无法从群集节点或本地＆＃34; 获取部署信息的方法。
答案 0 :(得分：0)
此错误表示无法在本地目录中找到指定的deployment.xml文件。您可以省略--config = deployment.xml并运行“voltdb init”，它将为您生成一个默认的deployment.xml文件。然后，如果您只想要一个具有默认设置的简单独立实例，则可以继续“voltdb start”。
或者，如果要修改配置设置，可以运行“voltdb init”来获取默认配置，然后运行“voltdb get deployment”以将生成的deployment.xml文件从voltdbroot目录检索到本地目录。然后你可以删除voltdbroot目录，修改这个deployment.xml文件并重新开始。您也可以重新使用手动生成的部署文件或从examples / HOWTOs / deployment-file-examples文件夹中复制的部署文件。
