Review Comment:
The `TESTS_PATH` points to `PyTest-KMS-EP` but the test directory is
`PyTest-KMS-HDFS`; update the path to the correct test folder.
```suggestion
TESTS_PATH="$HOME/Desktop/PyTest-KMS-HDFS"

Review Comment:
Fixed `sleep` delays can slow down tests and add flakiness; consider polling
the service for readiness instead of a blind 30s wait.

Review Comment:
Duplicate definition of `HDFS_USER`; remove the redundant assignment to
reduce confusion.
```suggestion
# Line 13 removed as it is redundant.

Review Comment:
[nitpick] Catching all exceptions can mask specific errors; consider
catching only the exceptions you expect (e.g., `subprocess.CalledProcessError`).
```suggestion
except subprocess.CalledProcessError as e:
return f"Failed to fetch logs from container. Command failed with
exit code {e.returncode}: {e.output}"
```
