安装Cloudera Manager出现的错误
1、hostname localhost.localdomain differs from the canonical name localhost
解决方法:
CentOS7查看hostname
CentOS6查看vim /etc/sysconfig/network
发现与/etc/hostname中的不一致
运行命令hostnamectl set-hostname XXX
2、MainThread agent ERROR Heartbeating to 192.168.1.217
解决这个问题简单的,是因为有进程占用了。比如
ps aux | grep super
kill 10215
/bin/systemctl stop cloudera-scm-agent.service
