centos安装cloudera-scm-agent启动失败,Failed to connect to previous supervisor

cloudera-scm-agent启动失败,查看日志文件var/log/cloudera-scm-agent/cloudera-scm-agent.log,发现如下

解决办法:

1、#ps -ef | grep supervisord   有supervisord残留

2、# kill  5925     杀死这个进程,但是过一会又有新的supervisord进程生成,问题无法解决

3、# kill -9 $(pgrep -f supervisord)  杀死监督者supervisor进程

4、卸载/var/run/cloudera-scm-agent/process

    # umount cm_processes

5、重启电脑,重新启动cloudera-scm-agent,成功
