Hi all,
Please vote on releasing the following candidate as Apache Mesos 0.28.0.
0.28.0 includes the following:
--------------------------------------------------------------------------------
* [MESOS-4343] - A new cgroups isolator for enabling the net_cls
subsystem in
Linux. The cgroups/net_cls isolator allows operators to provide network
performance isolation and network segmentation for containers within a
Mesos
cluster. To enable the cgroups/net_cls isolator, append
`cgroups/net_cls` to
the `--isolation` flag when starting the slave. Please refer to
docs/mesos-containerizer.md for more details.
* [MESOS-4687] - The implementation of scalar resource values (e.g., "2.5
CPUs") has changed. Mesos now reliably supports resources with up to
three
decimal digits of precision (e.g., "2.501 CPUs"); resources with more
than
three decimal digits of precision will be rounded. Internally, resource
math
is now done using a fixed-point format that supports three decimal
digits of
precision, and then converted to/from floating point for input and
output,
respectively. Frameworks that do their own resource math and manipulate
fractional resources may observe differences in roundoff error and
numerical
precision.
* [MESOS-4479] - Reserved resources can now optionally include "labels".
Labels are a set of key-value pairs that can be used to associate
metadata
with a reserved resource. For example, frameworks can use this feature
to
distinguish between two reservations for the same role at the same
agent
that are intended for different purposes.
* [MESOS-2840] - **Experimental** support for container images in Mesos
containerizer (a.k.a. Unified Containerizer). This allows frameworks to
launch Docker/Appc containers using Mesos containerizer without relying
on
docker daemon (engine) or rkt. The isolation of the containers is done
using
isolators. Please refer to docs/container-image.md for currently
supported
features and limitations.
* [MESOS-4793] - **Experimental** support for v1 Executor HTTP API. This
allows executors to send HTTP requests to the /api/v1/executor agent
endpoint without the need for an executor driver. Please refer to
docs/executor-http-api.md for more details.
Additional API Changes:
* [MESOS-4066] - Agent should not return partial state when a request is
made to /state endpoint during recovery.
* [MESOS-4547] - Introduce TASK_KILLING state.
* [MESOS-4712] - Remove 'force' field from the Subscribe Call in v1
Scheduler API.
* [MESOS-4591] - Change the object of ReserveResources and CreateVolume
ACLs to `roles`.
* [MESOS-4712] - Remove 'force' field from the Subscribe Call in v1
Scheduler API.
* [MESOS-4591] - Change the object of ReserveResources and CreateVolume
ACLs to `roles`.
* [MESOS-3583] - Add stream IDs for HTTP schedulers.
