我在安装Cloudera Manager（Ver 5.8.3）时遇到了麻烦。
我安装了cloudera-manager-agent-5.8.3-1.cm583.p0.8.el6.x86_64，Cloudera-Manager-Server-5.8.3-1.cm583.p0.8.el6.x86_64，Cloudera-Manager-Daemons-5.8.3-1.cm583.p0.8.el6.x86_64 on CentOS 6.5 64bit ->使用$ rpm -uvh [packagename]
并安装了mysql并设置conf file（/etc/cloudera-manager-server/db.properties）
但我联系了错误消息...
我不知道为什么遇到有关CM3的消息...
我只是安装了Cloudera-Manager 5.8.3，此版本不包含CM3 ...
我该如何解决这个问题？

我也面临同一问题。看来Cloudera在主机上的某个地方选择了一些旧版本的详细信息（可能是那里的CM3）。
我也找不到确切的原因，但是弹跳MySQL Server并重置这一切都帮助了我
