What's New in Hue

Learn about the new features of Hue in Cloudera Runtime 7.2.17.

Performance and security enhancements in Hue🔗

Python 2 has reached the end of life and is no longer supported. Hue now uses Python 3 which makes use of critical bug fixes and Common Vulnerabilities and Exposures (CVE) fixes for many third-party software dependencies. The following changes have been made in the Hue codebase in this release of CDP Public Cloud

Python libraries such as django-auth-ldap, django-axes, djangorestframework-simplejwt, Mako, Markdown, pyth on-ldap, django-babel, django-mako, django-cors-headers, djangorestframework, eventlet, sqlparse, and so on have been upgraded from Python 2.7 to Python 3.8.
The Django server has been upgraded from version 1.11.29 to 3.2.16.
Hue now uses Gunicorn as a front-end server. Previously, Hue used the CherryPy server.

These upgrades bring significant performance improvement and stability in query execution, uploading, and importing files to S3 or ABFS. Operating System, Python version, and Python module upgrades have resulted in a stable environment and fixed more than 800 security vulnerabilities.
