COS Filesystem

这个页面描述了如何让你的Hudi spark任务使用Tencent Cloud COS存储。

Tencent Cloud COS 部署

为了让Hudi使用COS，需要增加两部分的配置:

• 为Hidi增加Tencent Cloud COS的相关配置
• 增加Jar包的MVN依赖

Tencent Cloud COS 相关的配置

新增下面的配置到你的Hudi能访问的core-site.xml文件。使用你的COS bucket name替换掉fs.defaultFS，使用COS的key和secret分别替换fs.cosn.userinfo.secretKey和fs.cosn.userinfo.secretId。主要Hudi就能读写相应的bucket。
