错误原因：

• 创建索引失败，由日志错误信息可知在“/home/cloudera/datas/cloudera-scm-eventserver” 目录下创建索引失败。

解决方法：

• 进入CDH管理界面，打开 Cloudera Management Service 管理，查看配置，查看Event Server配置，Event Server 索引目录 选项，发现配置值与上述日志信息一样都是：/home/cloudera/datas/cloudera-scm-eventserver。

1. 先关闭CDH所有服务和停止Cloudera Management Service。
2. 进入服务器 /home/cloudera/datas/cloudera-scm-eventserver 目录，删除目录下所有文件：rm -rf ./*
3. 再次开启Cloudera Management Service服务，启动 Event Server。
4. 观察 Event Server 日志（/home/cloudera/logs/cloudera-scm-eventserver），查看有无错误，确认是否成功。

5. 看到如下界面，证明解决成功。
