What’s so great about Apache Ambari 2.7?

With Apache Ambari, our mission is to create and foster a 100% open source operations platform that allows teams to quickly deploy, secure, monitor and manage HDP, HDF, and our Hortonworks partner ecosystem products.  Whether you’re a customer with 5 nodes or 5,000, Apache Ambari gives you the enterprise feature set and tools needed to manage your entire Big Data portfolio.

The Ambari community worked incredibly hard to bring a ton of new features to completion with Ambari 2.7 release, and we’re excited for you to use them with our HDP 3.0 and HDF 3.2 & 3.3 products.

Ambari 2.7 Themes

With this release, we wanted to make Ambari more enjoyable to use every day, simplify finding and using our API, and unblock teams managing very large clusters.  Here is a preview of a few features we’re excited to share with you:

Revamped UI – Our Hortonworks Product Design Team has created a great new UI design system, and we’ve taken the time to update Ambari to use the new styles, colors, and navigation concepts from it.

Manage 5,000 node clusters – Our customer’s environments are growing rapidly and supporting large clusters has become ever more critical.  We completely redesigned how the Ambari Server, Agents, and UI communicate to allow multiple concurrent operators to use Ambari to manage some of the largest clusters on the planet.

A common task in large clusters is the need to perform bulk operations on multiple sets of nodes.  In this release, we’ve extended our bulk operations to bulk add/remove components such as DataNodes, NodeManagers, and RegionServers, and bulk delete hosts.  With great power comes great responsibility, so we’ve added extensive sanity checks and guardrails around this capability 😉

Simplify Security Configuration – Security is critical, and not altogether easy.  We’ve worked hard to make setting up Knox SSO simple allowing your users to easily use a single entry point and login to access essential cluster services.  We’ve also added support for using FreeIPA as a KDC with Ambari. Just like with Active Directory and MIT, Ambari will fully manage the principal creation, keytab generation/distribution, and configuration of Hadoop services to use Kerberos.

Easily find and use our API – Lots of our users make use of our rich API, but for a long time, you’ve had to be pretty motivated to discover just how powerful it is.  With this release, we have a REST API explore built into Ambari to allow you to quickly and easily find our API and use it to do great things.

Blueprint Export – Many Ambari users use our Blueprints API to export a complete picture of the cluster easily, and use that Blueprint to provision new clusters.  We’ve made it easier to export blueprints before and after deploying a cluster.  Now you can use a fresh Ambari install to spec out a new cluster and simply hit the “Generate Blueprint” button before deploying to export a complete blueprint.

Reduce “Papercuts” – Last year we spent time working with our field team, customers, and community to build up a list of small daily pain items that affected the productivity of our operators, we plowed through that list and loaded this release up with a lot of the small but meaningful fixes and improvements Ambari users have been asking for.

BUT WAIT, THERE’S MORE!
