Dataxtax代理错误 [英] Dataxtax Agent error
问题描述
在OpsCenter中添加现有群集时，收到错误：
While adding existing cluster in OpsCenter I receive an error:
ERROR: Agent for XXX.XXX.XXX.XXX was unable to complete operation (http://XXX.XXX.XXX.XXX:61621/snapshots/pit/properties?): java.lang.IllegalArgumentException: No implementation of method: :make-reader of protocol: #'clojure.java.io/IOFactory found for class: nil
在代理上有一个错误：
On agent there is an error:

推荐答案
代理所具有的问题是在该节点上找到DSE的安装。当它找不到DSE时，它无法获取归档属性文件更新和错误。
The problem the agent is having is finding your installation of DSE on that node. When it can't find DSE it can't get the archiving properties file to update and errors out.
这个错误消息是不幸的是没有帮助。我创建了一个票来修复错误消息（它是不幸的私人，但你可以使用这个票号码，当讨论与DataStax的问题：OPSC-4826）
This error message is unfortunately terribly unhelpful. I've created a ticket to fix the error message (it's unfortunately private, but you can use this ticket number when discussing the issue with DataStax: OPSC-4826)
解决方法，请尝试在该节点上的address.yaml文件中设置cassandra_install_location。调整address.yaml后，请退回代理，您可以重试该操作。
For a work around, try setting cassandra_install_location in your address.yaml file on that node. After adjusting address.yaml please bounce the agent and you can retry that operation.
您可以在此处找到列出此和更多address.yaml配置项的文档： http://www.datastax.com/documentation/opscenter/5.1/opsc/ configure / agentAddressConfiguration.html
You can find a document listing this and more address.yaml config items here: http://www.datastax.com/documentation/opscenter/5.1/opsc/configure/agentAddressConfiguration.html
