If you need to use COS filesystem for the dagger, provide the cos bucket/key configuration in the state.backend.fs.checkpointdir, state.savepoints.dir, high-availability.storageDir to flinkdeployment manifest.

If the filesystem protocol begins with cosn for the above configurations, dagger uses the below configurations provided in the flinkdeployment manifest file.

    fs.cosn.impl: org.apache.hadoop.fs.CosFileSystem
    fs.AbstractFileSystem.cosn.impl: org.apache.hadoop.fs.CosN
    fs.cosn.userinfo.secretId: <secretID>
    fs.cosn.userinfo.secretKey: <secretKey>
    fs.cosn.bucket.region: <region>
    fs.cosn.bucket.endpoint_suffix: <tencent-provided-prefix.xyz.com>
