您好,我正在尝试从卡桑德拉提取数据使用AWS胶水和编写PySpark代码。下面是代码,给了我错误。请建议我如何导入类/驱动程序。 我想从Cassandra中提取并创建文件到S3存储桶中。 #from awsglue.transforms import sys

最近我开始将我的项目发布到Sonatype存储库,但当我确实执行了一个发布时,我可以从我的构建日志中看到它确实成功地发布到了staging: info] published csv-parser_2.12 to https://oss.sonatype.org/service/local/staging/deploy/maven2/com/bigelectrons/joesan/csv-parser_2.12/0.2.0/csv-parser_2.12-0.2.0-javadoc.jar

我有一个服务器,我需要检查服务器温度,所以我简单地决定使用传感器包,使用zypper安装它。所以
首先,我通过根用户使用zypper install sensors命令,结果消息是:Loading repository data... Reading installed packages... Resolving package dependencies... The following NEW package is going to be installed: sensors Overall download size: 84.0 K. After the operation, additi

//loop and select objects which fit criteria
oa & object[i];
现在如何返回(查找)并将实际值(i)放在序列化存档中的占位符(number_of_objects)的位置?
我喜欢FTP/WebDAV的Nautilus,但是如何将它与FTPS服务器一起使用呢?
当我进入ftps://时,Don't recognize this file server type说。
有插件吗?
或者像Nautilus这样快速方便的东西,在FTPS的支持下?
来自Ubuntu回购公司的gFTP说,FTPS Support unavailable since SSL support was not compiled in。
请注意:不应将FTPS与SSH文件传输协议(SFTP)混淆,这是安全Shell (SSH)协议的一个不兼容的安全文件传输子系统。它也不同于安全FTP,通过
