| |
| <p>Full release notes are available in the release <a href="https://git-wip-us.apache.org/repos/asf?p=incubator-aurora.git&f=CHANGELOG&hb=0.6.0-rc2">CHANGELOG</a>.</p> |
| |
| <h2 id="highly-available,-scheduler-driven-updates">Highly-available, scheduler-driven updates</h2> |
| |
| <p>Rolling updates of services is a crucial feature in Aurora. As such, we |
| want to take great care when changing its behavior. Previously, Aurora operated |
| by delegating this functionality to the client (or any API client, for that |
| matter). In this version, the scheduler can take over the |
| responsibility of application update orchestration. Further details were discussed on the <a href="http://mail-archives.apache.org/mod_mbox/incubator-aurora-dev/201407.mbox/%3CCAGRA8uMxwVDokp_iHXhNru2gd-x_nM%2BDYAurpfAO6wuX7%3DnHFw%40mail.gmail.com%3E">Aurora mailing list</a>.</p> |
| |
| <h2 id="aurora-web-ui-improvements">Aurora Web UI Improvements</h2> |
| |
| <p>Since the scheduler can now orchestrate job updates, it has awareness of the progress and outcome of updates. This means you can see a progress bar for in-flight updates, and the history of updates for your jobs. Additionally, the performance of the UI was improved, especially for large roles and jobs <a href="https://issues.apache.org/jira/browse/AURORA-458">AURORA-458</a>.</p> |
| |
| <h2 id="service-announcement-and-management">Service Announcement and Management</h2> |
| |
| <p>Job configurations can now supply an <a href="http://aurora.incubator.apache.org/documentation/latest/configuration-reference/#announcer-objects"><code>announce</code> parameter</a>, which is meant to be a way to opt-in for registration in a service discovery system. This has been implemented in the Aurora executor, and will automatically announce tasks via ZooKeeper.</p> |
| |
| <h2 id="aurora-client-improvements">Aurora Client Improvements</h2> |
| |
| <p>Progress was made in features to <a href="http://aurora.incubator.apache.org/documentation/latest/clientv2/">v2</a> of the <a href="http://aurora.incubator.apache.org/documentation/latest/client-commands/">Aurora client</a>. We will support version 1 and version 2 for 0.6.0, with version 1 to be removed in 0.7.0.</p> |
| |
| <h2 id="improved-project-documentation">Improved Project Documentation</h2> |
| |
| <p>New documentation pages including:</p> |
| |
| <ul> |
| <li><a href="http://aurora.incubator.apache.org/documentation/latest/deploying-aurora-scheduler/">Deploying the Aurora scheduler</a></li> |
| <li><a href="http://aurora.incubator.apache.org/documentation/latest/cron-jobs/">Cron jobs</a></li> |
| <li><a href="http://aurora.incubator.apache.org/documentation/latest/sla/">SLA measurement</a></li> |

| <li><a href="http://aurora.incubator.apache.org/documentation/latest/monitoring/">Monitoring</a></li> |
| </ul> |
| |
| <h2 id="getting-involved">Getting Involved</h2> |

| <p class="disclaimer">Apache Aurora is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.</p> |
