Tencent Cloud

In this page, we explain how to get your Hudi spark job to store into Tencent Cloud COS.

Tencent Cloud COS configs

There are two configurations required for Hudi-COS compatibility:

• Adding Tencent Cloud COS Credentials for Hudi
• Adding required Jars to classpath

Tencent Cloud COS Credentials

Add the required configs in your core-site.xml from where Hudi can fetch them. Replace the fs.defaultFS with your COS bucket name, replace fs.cosn.userinfo.secretId with your COS secret Id, replace fs.cosn.userinfo.secretKey with your COS key. Hudi should be able to read/write from the bucket.
