CDH Oozie 邮件配置
- 准备工作，邮件操作 SMTP 配置
- 使用微信企业邮箱进行配置，执行测试任务时报错：Encountered an error while sending the email message over SMTP，错误原因是配置 Oozie 邮箱操作 SMTP 身份验证密码时错误，根据文档多次测试没有成功，改为 163 邮箱，一次性配置成功。
- 网易 163 邮箱配置步骤
关键路径：
设置——> POP3/SMTP/IMAP
开启 SMTP 服务（截图中已经是开启状态，所以显示 关闭），按提示一步步操作，最后生成授权码，用于登录第三方邮件客户端的专用密码，在下面的“Oozie 电子邮件操作 SMTP 身份验证密码” 中使用此授权码
到这一步，准备工作完成。
- 从 Cloudera Manager 进入 Oozie 配置，输入 email
cdh-ooize-email
- 配置邮件相关字段
cdh-ooize-email-config
- Oozie 电子邮件操作 SMTP 主机：即邮件服务器主机名，比如smtp.163.com、smtp.qq.com 等
- Oozie 电子邮件操作发件人地址：邮件发件人地址，如 xxx.163.com
- 启用身份验证
- Oozie 电子邮件操作 SMTP 身份验证用户名：可以使用与2一样的地址 xxx.163.com
- Oozie 电子邮件操作 SMTP 身份验证密码，不是邮箱密码
- Oozie 启用 SLA
cdh-ooize-sla-config
- 重启 Oozie 使得配置生效
通过 Hue 配置工作流 SLA
- 点击 Workflows 的 settings 按钮，Enable SLA Configuration后，输入收件人邮件地址
- 测试邮件效果

错误原因
配置 Oozie 邮箱操作 SMTP 身份验证密码时错误，这个密码是启动 SMTP 服务时在邮箱设置的授权码，并不是邮箱密码。
解决方案
CDH Oozie 邮件配置由微信企业邮箱改为 163 邮箱。
