Cloudera Manager未能启动活动监视器

我从here下载了CDH 4.5快速启动虚拟机。每个服务看起来除了我打开活动选项卡后，查看mapreduce的活动，看到下面的错误好：Cloudera Manager未能启动活动监视器

The Activity Monitor server (activitymonitor (localhost)) is unavailable or not responding to connections.

问题仍然之后我试图重新启动活动监控服务，那么我在日志中发现以下错误消息。任何人都可以帮忙看看吗？

“java.net.BindException：已在使用中的地址”清楚地表明端口9999已被其他服务占用。您必须检查服务的PID并将其停止：

lsof -P | grep LISTEN | grep的9999

使用kill命令来杀死或者，如果你知道该服务，然后停止正常

谢谢，原来是水槽使用同一端口。停止渠道服务后，活动监视器可以无任何问题地启动。 – zhutoulala
