🎉 Apache Ambari 3.0.0 Released: A New Chapter in Hadoop Cluster Management

#hadoop #apache #devops #bigdata

Hey there, fellow developers! 👋

Exciting news from the Apache Ambari community - we've just released version 3.0.0! This release is not just another version bump - it's a testament to the resilience of the open source community and marks a significant milestone in our journey.

💪 A Story of Community Resilience

Before diving into the features, I want to share something important with you. This release represents more than just new features - it's our first major release since HDP (Hortonworks Data Platform) became closed source. The journey hasn't been easy:

🔄 We've gone through major community restructuring
👥 Our contributor base significantly reduced
🛠 We faced critical infrastructure challenges, especially with RPM distribution
🔨 We had to rebuild everything after Hortonworks merged with Cloudera and HDP went closed source

But here's the thing - despite all these challenges, our community stood strong. We kept pushing forward, driven by one goal: not to let down the users who've been patiently waiting for this release. This release is as much yours as it is ours - a testament to the power of open source spirit and community dedication.

Apache Bigtop Integration

The biggest change is that Ambari now uses Apache Bigtop as its default packaging system. This means a more sustainable and community-driven approach to package management. If you're a developer working with Hadoop components, this is going to make your life much easier!

📢 Important Note About Downloads

Hey folks, a quick heads-up about the downloads! Due to the size of our RPM packages (about 10GB+ for each OS), Apache's infrastructure isn't suitable for hosting them. As a temporary solution, I'm personally hosting these files on my own server. However, there's a monthly bandwidth limit of 3TB due to budget constraints.

To help ensure everyone can access the files:

💾 If you've already downloaded, consider sharing via Google Drive or similar platforms
🤝 Share download links with your peers if you have them
🌟 Help spread the load by mirroring the files if you can

We're working on getting sponsorship to upgrade the server capacity. If you or your organization would like to sponsor this effort, please reach out to jialiangcaimd@gmail.com. Until then, let's help each other out - that's what open source is all about!
