报错：Error, CM server guid updated, expected xxxxx, received xxxxx (未解决)
报错背景：
CDH断电重启后，cloudera-scm-server启动报错，
cloudera-scm-server 已死，但 pid 文件仍存
由于没有成熟的解决方案，于是我就重新安装了MySQL数据库，
并且重新赋予了各种权限。
这个时候cloudera-scm-server可以启动成功，cloudera-scm-agent也可以启动成功。
报错现象：
此时cloudera-scm-server和cloudera-scm-agent都能启动成功，
但是jps一下，没有服务
明明启动了agent，但是下面的服务都起不来。
报错原因：
这个时候就要看一下日志文件cloudera-scm-agent.log
tail -n 100 /opt/cm-5.15.1/log/cloudera-scm-agent/cloudera-scm-agent.log
看到一行报错

日志文件
意思就是：CM服务器guid更新，期望f4ec230a-2f55-460f-b132-cb45a16c3a1b，收到4760feb5-8e8c-416c-8337-2910fef890a0
一看就是和CM的guid有关系，所以就从这方面着手解决问题。
报错解决：
[root@master var]# find / -name cm_guid # 找到cm_guid这个文件所在的目录 /opt/cm-5.15./lib/cloudera-scm-agent/cm_guid [root@master var]# rm -rf /opt/cm-5.15./lib/cloudera-scm-agent/cm_guid # 删除这个目录（所有节点） [root@master var]# /opt/cm-5.15./etc/init.d/cloudera-scm-agent restart # 重启
但是重启之后，jps还是没有各个服务进程
再次查看报错日志

报错日志
报错信息：ERROR Error getting directory attributes for /opt/cm-5.15.1/log/cloudera-scm-agent
日志翻译：错误获取/opt/cm-5.15.1/log/cloudera-scm-agent的目录属性时出错
这个报错我找了很多资料也没有解决。
但是我发现一个现象，就是进到CDH的Web界面之后，由于uuid的改变，原来的界面都没有了，需要重新安装各种服务。
我看到这里就崩溃了，重装的CDH。
