Data Lake File Property Inspector

Build a tool that retrieves and reports properties of files and directories in Azure Data Lake Storage Gen2.

Requirements

Your solution must:

1. Connect to an Azure Data Lake Storage account and access a specified file system
2. Retrieve detailed properties for a given file path, including:
   • File size and last modified timestamp
   • Content type and other HTTP headers
   • Metadata key-value pairs
   • POSIX permissions and access control information
3. Retrieve properties for a directory path, including:
   • Creation and last modified times
   • Metadata
   • Owner and group information
4. Handle both files and directories correctly based on the path type
5. Format and display the retrieved properties in a human-readable way

Input

Your program should accept:

• Connection information (connection string or account credentials)
• File system name
• Path to inspect (file or directory)

Output

Display the properties in a structured format showing:

• Path type (file or directory)
• All available properties retrieved from the storage service
• Clear labels for each property

Constraints

• Use proper error handling for missing paths or connection failures
• Support both file and directory path types
• Retrieve comprehensive property information available from the service

Test Cases

Test Case 1: Retrieve File Properties { .test }

File: test_file_properties.py { .test-file }

Test: Given a valid file path in a file system, retrieve and verify that file properties include size, last modified time, content type, and metadata. { .test-case }

Test Case 2: Retrieve Directory Properties { .test }

File: test_file_properties.py { .test-file }

Test: Given a valid directory path in a file system, retrieve and verify that directory properties include creation time, owner information, and metadata. { .test-case }

Test Case 3: Handle Non-Existent Path { .test }

File: test_file_properties.py { .test-file }

Test: When requesting properties for a non-existent path, the program should handle the error gracefully and provide a clear error message. { .test-case }
