This PR adds support for SAS (Shared Access Signature) token authentication
in the ADLSGen2PinotFS plugin, providing an additional authentication method
for Azure Data Lake Storage Gen2.
Changes Made:
- Enhanced Authentication Options: Added SAS token authentication as a new
authentication type alongside existing methods (default
credential, client secret)
- Configuration Support: Added sasToken configuration property to specify
the SAS token
- Added unit tests to verify SAS token authentication functionality and
error handling
Configuration Usage:
To use SAS token authentication, configure the following properties:
```
# Authentication type
authenticationType=SAS_TOKEN
# Required: SAS token for authentication
sasToken=sp=rwdl&se=2025-12-31T23:59:59Z&sv=2022-11-02&sr=c&sig=your-signature-here
# Required: Azure storage account name
accountName=your-storage-account-name
# Required: File system/container name
fileSystemName=your-container-name
# Optional: Proxy configuration (if needed)
proxyHost=proxy.company.com
proxyPort=8080
proxyUsername=proxy-user
proxyPassword=proxy-pass
```
Example SAS Token Format:
```
sp=rwdl&se=2025-12-31T23:59:59Z&sv=2022-11-02&sr=c&sig=abcdef123456...
```
Where:
- sp=rwdl - Permissions (read, write, delete, list)
- se= - Expiry date/time
- sv= - API version
- sr=c - Resource type (container)
- sig= - Signature
Benefits:
- Simplified Authentication: No need to manage service principal
credentials or client secrets
- Fine-grained Access: SAS tokens can be scoped to specific containers and
operations
- Time-bound Access: Built-in expiration for enhanced security
- Corporate Friendly: Easier to integrate with corporate security policies
Validation:
The implementation includes proper validation to ensure required
parameters (accountName, sasToken) are provided and throws appropriate
exceptions when missing.
