解决办法是在这里找到的：https://groups.google.com/a/cloudera.org/forum/#!topic/scm-users/9iEmaJELI44
I‘d recommend moving /var/lib/cloudera-scm-eventserver to /var/lib/cloudera-scm-eventserver-old and restart event server. You‘ll lose historical health data and other events. CM will recreate the dir on restart.
即执行 mv /var/lib/cloudera-scm-eventserver /var/lib/cloudera-scm-eventserver-old
然后再启动服务即可。
ClouderaManager的其他服务有问题时，也可同样如何处理
ClouderaManager中Event Server报No such file or directory
