Deleting Access Labels
Function
This API deletes access labels of a PFS directory.
If you have any questions during development, post them on the Issues page of GitHub.
Restrictions
- Calling this API requires permissions, which can be granted by using IAM or policies. If IAM is used, the obs:bucket:DeleteAccessLabel permission must be granted. For details, see Introduction to OBS Access Control, IAM Custom Policies, and Configuring an Object Policy.
- The mapping between OBS regions and endpoints must comply with what is listed in Regions and Endpoints.
- This API is currently available only for PFSs. Object buckets do not support this API. For details about how to create a PFS, see Creating a Parallel File System (SDK for Java).
- Access labels can be set for directories in a PFS but cannot be set for the PFS itself or files therein.
