Apache Mesos 0.24.0 Released
The latest Mesos release, 0.24.0, is now available for download. This release includes the following features and improvements:
Scheduler HTTP API (MESOS-2288)
Mesos 0.24 provides experimental support for scheduler HTTP API. Framework schedulers can communicate with Mesos by sending HTTP POST requests to
/api/v1/scheduler instead of depending on the native libmesos library. The endpoint accepts both JSON and Protobuf requests. Additionally, the master talks back to the scheduler using the same connection opened by the scheduler, mitigating communication issues in firewalled/NATed environments. Refer to the scheduler http api documentation for more information.
Note that, this release only adds the support for scheduler HTTP API. Support for HTTP executor API is currently in the works and will be released soon!
API Versioning (MESOS-3167)
As part of this release, we have also outlined the versioning scheme for Mesos HTTP API going forward. At a high level, the Mesos API (constituting Scheduler, Executor, Internal, Operator/Admin APIs) will have a version in the URL. The versioned URL will have a prefix of
N is the version of the API. For simplicity, the stable version of the API will correspond to the major release version of Mesos. For example, v1 of the API will be supported by Mesos release versions 1.0.0, 1.4.0, 1.20.0 etc. Refer to the versioning design document for more information.
Hundreds of other bug fixes/improvements are included in Mesos 0.24.0. See the CHANGELOG for a full list of resolved JIRA issues.
Rolling upgrades from a Mesos 0.23.x cluster to Mesos 0.24 are straightforward, but there are a few caveats/deprecations. Please refer to the upgrade guide for detailed information on upgrading to Mesos 0.24.
