This is the main directory for testing HDFS encryption cycle

Structure

test_hdfs/
├── test_encryption.py
├── test_encryption02.py  
├── test_encryption03.py
├── test_config.py        #stores all constants and HDFS commands
├── conftest.py           #sets up the environment
├── utils.py              #utility methods

Features

  • Markers:
    Markers can be used to selectively run specific test cases, improving test efficiency and organization.

setup_environment

Handled in conftest.py file Before running the test cases, some environment configurations are needed:

  • HDFS must communicate with KMS to fetch key details.
  • Specific KMS properties are added to the core-site.xml file.
  • Containers are restarted to apply the changes effectively.

Utility Methods

  • get_error_logs:
    Fetches logs from both KMS and HDFS containers. Helps in identifying issues when errors or exceptions occur during testing.

  • run_command:
    Executes all necessary HDFS commands inside the containers.

test_encryption.py

Handles the full HDFS encryption cycle, including setup, positive and negative test scenarios, and cleanup.

Main Highlights:

  • Encryption Zone (EZ) creation in HDFS.
  • Granting permissions to specific users for read/write operations within the EZ.
  • Validating read/write attempts by unauthorized users inside the EZ.

test_encryption02.py

Handles the Check if after key roll over old files can be read or not Check if after key roll over new files can be written and read too Check read operation on file after key deletion

test_encryption03.py

Handles the Test case on cross Encryption zone operations

Summary

This test suite ensures that HDFS encryption and access control mechanisms function as expected, validating both authorized and unauthorized access scenarios.
