0、最近公司在上微软云，需要把数据推到Azure EventHub kafka1、这是我谷歌网上找的资料（我没试过）。看了下比较靠谱。加上国内比较少这方面的资 料就把连接复制到这https://stackoverflow.com/questions/63226387/connect-to-azure-eventhubkafka-like-with-spring-boot-using-connect

有3年没有写spark了一切都是这么陌生MD. 今天跑下还报错，解决参考：https://stackoverflow.com/questions/40609771/queries-with-streaming-sources-must-be-executed-with-writestream-start

pip intarll　报错　　error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\cl.exe' failed with exit code 2

1、目录只能建软连接2、建立的时候参数都要绝对路径3、示例：ln -s /var/www/HDP-UTILS /home/data/package/HDP-UTILS

1、今天安装kettle 起动的时候如下警告no libwebkitgtk-1.0 detected, some features will be unavailableConsider installing the package with apt-get or yum.e.g. 'sudo apt-get install libwebkitgtk-1.0-0'2、因为我用的是centos7.x

时间小于多少删除数据POST sms_index/_delete_by_query{"query": {"range": {"auditTime": {"lt":"2020-03-14T03:09:11.989Z"}}}}
