Announcing Apache Slider 0.60.0

Hortonworks architects vertically integrate the projects within our Hadoop distribution with YARN and HDFS in order to enable HDP to span workloads from batch, interactive, and real time—across both open source and other data access technologies. In HDP 2.2, we deliver work to vertically integrate Apache Storm, Apache Accumulo and Apache HBase so that all of those long-running services run in Hadoop on YARN via Apache Slider.

The Apache Slider community recently released Apache Slider 0.60.0. Although there are many new features in Apache Slider 0.60.0, four new innovations are particularly notable:

  • Application onboarding without code changes
  • Dynamic application scaling
  • A registry for dynamic lookup of application configurations
  • Integration with Apache Ambari

Here are some details about those four important features. For the complete list of features, improvements, and bug fixes, see the release notes.

Application onboarding without code changes

Existing long-running applications can be difficult to update for deployment on a Hadoop cluster. The new framework in Apache Slider provides a way to leverage YARN’s resource management capabilities. Now cluster administrators can onboard existing long-running data access applications, without changes to their code or API implementations. This allows consolidation of all edge clusters onto a single, unified Hadoop cluster.

Dynamic application scaling

Scale applications in Slider on demand with the ability to increase and decrease component instance containers. Now you can easily suspend or resume applications with Slider. These changes provide new application elasticity and agility, which improves cluster utilization and reduces total cost of ownership.

Registry for dynamic lookup of application configurations

Apache Ambari now has a View called “Slider App View.” This shows all the apps running through Slider, with their related details, providing a single, integrated management interface for all Slider-enabled applications.

Coming Next in Slider

The Slider community plans to develop some exciting new capabilities for the next release, including:

  • Additional developer tools
  • Support for Docker as a package
  • Support for repeatable, short-lived services
  • Application relocation for Backup and Recover & Test-to-Production
  • “Slider Local” for local testing and debugging
  • Rolling upgrade capabilities for applications in Slider
  • Onboarding of Apache Solr and Apache Kafka onto YARN via Slider

We want to thank the Apache HBase, Accumulo, and Storm communities for their work to enable those powerful long-running applications with Slider. We also thank the Apache Ambari community for providing the management view for Slider.
