Apache Ambari 3.0.0 Release Notes

Overview​

Major Release

Apache Ambari 3.0.0 represents a significant milestone in the project's development, bringing major improvements to cluster management capabilities, user experience, and platform support. This release focuses on modernizing the technology stack, enhancing security features, and improving overall stability and performance.

Acknowledgment and Important Notes​

A Message to Our Community​

Important Transition

We want to acknowledge that Ambari 3.0 represents a significant milestone as the first major release since the HDP project became closed source. Due to this transition, we have made some important decisions:

  • The 2.7.x series has reached End-of-Life (EOL) and will no longer be maintained, as we no longer have access to the HDP packaging source code.
  • Version 3.0 marks the beginning of our new mainline branch, which will receive primary maintenance and development focus.

From Our Hearts to the Community​

A Journey Together

The path to this release has been long and challenging. Our community has weathered significant changes and obstacles:

  • 🔄 Community restructuring and transitions
  • 👥 A significantly reduced contributor base
  • 🛠 Critical infrastructure challenges, especially around RPM distribution

Thank You

To every user who has stood by Ambari through these times: your patience and understanding mean more to us than words can express. We know this release has been a long time coming, and we are truly sorry for keeping you waiting.

With Gratitude

Our hearts are filled with gratitude for:

  • 🌟 The pioneers who laid Ambari's foundation
