      <description>&lt;p&gt;Hey there, fellow developers! 👋 &lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;

&lt;h2&gt;
  
  
  💪 A Story of Community Resilience
&lt;/h2&gt;

&lt;p&gt;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:&lt;/p&gt;

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

&lt;p&gt;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.&lt;/p&gt;

&lt;h2&gt;
  
  
  🌟 What's New?
&lt;/h2&gt;

&lt;p&gt;&lt;a href="https://ambari.apache.org/docs/3.0.0/release-notes/" rel="noopener noreferrer"&gt;https://ambari.apache.org/docs/3.0.0/release-notes/&lt;/a&gt;&lt;/p&gt;

&lt;h3&gt;
  
  
  Apache Bigtop Integration
&lt;/h3&gt;

&lt;p&gt;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!&lt;/p&gt;

&lt;h3&gt;
  
  
  Platform Support Galore 🚀
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;✅ Rocky Linux 8 and 9 support&lt;/li&gt;
&lt;li&gt;✅ openEuler-22.03 support&lt;/li&gt;
&lt;li&gt;☕️ Java 17 support (yes, finally!)&lt;/li&gt;
&lt;li&gt;🗄 MySQL 8 support for Hive&lt;/li&gt;
&lt;li&gt;📈 Upgrade to python3&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;
  
  
  New Services &amp;amp; Components 🛠
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;strong&gt;Alluxio&lt;/strong&gt;: New distributed file system support&lt;/li&gt;
&lt;li&gt;
&lt;strong&gt;Livy&lt;/strong&gt;: Now available as an individual service&lt;/li&gt;
&lt;li&gt;
&lt;strong&gt;Ranger KMS&lt;/strong&gt;: Enhanced security features&lt;/li&gt;
&lt;li&gt;
&lt;strong&gt;YARN Timeline Service V2&lt;/strong&gt;: Better job history tracking&lt;/li&gt;
&lt;li&gt;
&lt;strong&gt;DFSRouter&lt;/strong&gt;: Easy access via the HDFS summary page&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;
  
  
  Monitoring Just Got Better 📊
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;New Grafana dashboards for better visualization&lt;/li&gt;
&lt;li&gt;Improved metrics collection and display&lt;/li&gt;
&lt;li&gt;Better performance with reduced websocket connections&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;
  
  
  Security First 🔒
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;Major dependency upgrades to address CVEs&lt;/li&gt;
&lt;li&gt;Enhanced password validation&lt;/li&gt;
&lt;li&gt;Improved SSL cipher configurations&lt;/li&gt;
&lt;li&gt;Knox SSO login improvements&lt;/li&gt;
&lt;/ul&gt;

&lt;h2&gt;
  
  
  🎯 Who Should Care?
&lt;/h2&gt;

&lt;p&gt;If you're:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Managing Hadoop clusters&lt;/li&gt;
&lt;li&gt;Working with big data infrastructure&lt;/li&gt;
&lt;li&gt;Looking for better cluster management tools&lt;/li&gt;
&lt;li&gt;Interested in modern Hadoop ecosystem&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;Then this release is definitely for you!&lt;/p&gt;

&lt;h2&gt;
  
  
  📢 Important Note About Downloads
&lt;/h2&gt;

&lt;p&gt;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.&lt;/p&gt;

&lt;p&gt;To help ensure everyone can access the files:&lt;/p&gt;

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

&lt;p&gt;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 &lt;a href="mailto:jialiangcaimd@gmail.com"&gt;jialiangcaimd@gmail.com&lt;/a&gt;. Until then, let's help each other out - that's what open source is all about! &lt;/p&gt;

&lt;h2&gt;
  
  
  🚀 Getting Started
&lt;/h2&gt;

&lt;p&gt;Ready to try it out? Here's how:&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Download from &lt;a href="https://apache-ambari.com/download/" rel="noopener noreferrer"&gt;Apache Ambari Download Page&lt;/a&gt;
&lt;/li&gt;
&lt;li&gt;Check compatibility:

&lt;ul&gt;
&lt;li&gt;OS: Rocky Linux 8/9, openEuler-22.03&lt;/li&gt;
&lt;li&gt;DB: PostgreSQL 10+, MySQL 5.7+/8+, MariaDB 10.2+&lt;/li&gt;
&lt;/ul&gt;
&lt;/li&gt;
&lt;/ol&gt;

&lt;h2&gt;
  
  
  🔮 What's Next?
&lt;/h2&gt;

&lt;p&gt;And here's a little sneak peek at what's coming in the next minor release:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;🌱 Spring Framework 6 upgrade for better performance and security&lt;/li&gt;
&lt;li&gt;🐳 One-click cluster deployment with Docker automation&lt;/li&gt;
&lt;li&gt;...and more exciting features in the pipeline!&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;Stay tuned - the future of Ambari is looking bright! &lt;/p&gt;
