Datastax OpsCenter 3.1.1代理JMX身份validation错误

我正在使用opscenter 3.1.1，并在我的Cassandra集群上启用了JMX用户名/密码身份validation。 我想我已经更新了所有我的opscenterconfiguration正确强制代理使用JMX身份validation，但它不工作。

我使用以下jmx属性更新了/etc/opscenter/Clusters/[cluster-name].conf下的configuration

  [jmx] username=username password=password port=7199 

然后，我重新启动了opscenter和opscenter代理，但在opscenter代理日志中看到以下错误：

  DEBUG [Thread-10] 2013-11-15 10:07:28,461 Adding JMX connector to pool (127.0.0.1:7199) DEBUG [node-details-1] 2013-11-15 10:07:28,464 Starting real-time collection DEBUG [node-details-2] 2013-11-15 10:07:28,466 Starting short-time collection DEBUG [node-details-3] 2013-11-15 10:07:28,468 Starting long-time collection ERROR [node-details-1] 2013-11-15 10:07:28,474 Error getting realtime node details java.lang.SecurityException: Authentication failed!

在这个stacktrace上面的几行，我看到一行说代理正在从opscenter中检索最新的configuration：

  INFO [StompConnection receiver] 2013-11-15 10:07:18,298 Got new config from OpsCenter: 

但是数据中唯一与jmx相关的属性是:jmx_port 7199 。

这似乎是3.2.2中的一个错误（ http://mail-archives.apache.org/mod_mbox/cassandra-user/201310.mbox/%3CCALHkrw_xjJBy5k-7vCc3NezLy17HLY_HPDCFptG74RqiivcgBg@mail.gmail.com%3E ），但我看到没有迹象表明它是3.1.1中的一个bug，或者它已经被修复为4.0。

有想法该怎么解决这个吗？
