Subject [VOTE] Release Apache Mesos 1.0.0 (rc2)
Date Fri, 08 Jul 2016 01:35:41 GMT
Hi all,


Please vote on releasing the following candidate as Apache Mesos 1.0.0.


1.0.0 includes the following:

--------------------------------------------------------------------------------

  * Scheduler and Executor v1 HTTP APIs are now considered stable.





  * [MESOS-4791] - **Experimental** support for v1 Master and Agent APIs.
These

    APIs let operators and services (monitoring, load balancers) send HTTP


    requests to '/api/v1' endpoint on master or agent. See


    `docs/operator-http-api.md` for details.





  * [MESOS-4828] - **Experimental** support for a new `disk/xfs' isolator


    has been added to isolate disk resources more efficiently. Please refer
to

    docs/mesos-containerizer.md for more details.





  * [MESOS-4355] - **Experimental** support for Docker volume plugin. We
added a

    new isolator 'docker/volume' which allows users to use external volumes
in

    Mesos containerizer. Currently, the isolator interacts with the Docker


    volume plugins using a tool called 'dvdcli'. By speaking the Docker
volume

    plugin API, most of the Docker volume plugins are supported.





  * [MESOS-4641] - **Experimental** A new network isolator, the


    `network/cni` isolator, has been introduced in the
`MesosContainerizer`. The

    `network/cni` isolator implements the Container Network Interface (CNI)


    specification proposed by CoreOS.  With CNI the `network/cni` isolator
is

    able to allocate a network namespace to Mesos containers and attach the


    container to different types of IP networks by invoking network drivers


    called CNI plugins.





  * [MESOS-2948, MESOS-5403] - The authorizer interface has been refactored
in

    order to decouple the ACLs definition language from the interface.


    It additionally includes the option of retrieving `ObjectApprover`. An


    `ObjectApprover` can be used to synchronously check authorizations for
a

    given object and is hence useful when authorizing a large number of
objects

    and/or large objects (which need to be copied using request based


    authorization). NOTE: This is a **breaking change** for authorizer
modules.




  * [MESOS-5405] - The `subject` and `object` fields in
authorization::Request

    have been changed from required to optional. If either of these fields
is

    not set, the request should only be authorized if any subject/object
should

    be allowed.

    NOTE: This is a semantic change for authorizer modules.





  * [MESOS-4931, MESOS-5709, MESOS-5704] - Authorization based HTTP
endpoint

    filtering enables operators to restrict what part of the cluster state
a

    user is authorized to see.


    Consider for example the `/state` master endpoint: an operator can now


    authorize users to only see a subset of the running frameworks, tasks,
or

    executors. The following endpoints support HTTP endpoint filtering:


    '/state', '/state-summary', '/tasks', '/frameworks','/weights',


    and '/roles'. Additonally the following v1 API calls support filtering:


    'GET_ROLES','GET_WEIGHTS','GET_FRAMEWORKS', 'GET_STATE', and
'GET_TASKS'.




  * [MESOS-4909] - Tasks can now specify a kill policy. They are
best-effort,

    because machine failures or forcible terminations may occur. Currently,
the

    only available kill policy is how long to wait between graceful and
forcible

    task kill. In the future, more policies may be available (e.g. hitting
an

    HTTP endpoint, running a command, etc). Note that it is the executor's


    responsibility to enforce kill policies. For executor-less
command-based

    tasks, the kill is performed via sending a signal to the task process:


    SIGTERM for the graceful kill and SIGKILL for the forcible kill. For
docker

    executor-less tasks the grace period is passed to 'docker stop --time'.
This

    feature supersedes the '--docker_stop_timeout', which is now
deprecated.




  * [MESOS-4908] - The task kill policy defined within 'TaskInfo' can now
be

    overridden when the scheduler kills the task. This can be used by
schedulers

    to forcefully kill a task which is already being killed, e.g. if
something

    went wrong during a graceful kill and a forcible kill is desired. Note
that

    it is the executor's responsibility to honor the
'Event.kill.kill_policy'

    field and override the task's kill policy and kill policy from a
previous

    kill task request. To use this feature, schedulers and executors must


    support HTTP API; use the '--http_command_executor' agent flag to
ensure

    the agent launches the HTTP API based command executor.





  * [MESOS-4949] - The executor shutdown grace period can now be configured
in

    `ExecutorInfo`, which overrides the agent flag. When shutting down an


    executor the agent will wait in a best-effort manner for the grace
period

    specified here before forcibly destroying the container. The executor
must

    not assume that it will always be allotted the full grace period, as
the

    agent may decide to allot a shorter period and failures / forcible


    terminations may occur. Together with kill policies this gives
frameworks

    flexibility around how to clean up tasks and executors.




  * [MESOS-3094] - **Experimental** support for launching mesos tasks on


    Windows. Note that there are no isolation guarantees provided yet.





  * [MESOS-4090] - The `mesos.native` python module has been split into
two,

    `mesos.executor` and `mesos.scheduler`. This change also removes


    un-necessary 3rd party dependencies from `mesos.executor` and


    `mesos.scheduler`. `mesos.native` still exists, combining both modules
for

    backwards compatibility with existing code.





  * [MESOS-1478] - Phase I of the Slave to Agent rename is complete. To
support

    the rename, new duplicate flags (e.g., --agent_reregister_timeout), new


    binaries (e.g., mesos-agent) and WebUI sandbox links have been added.
All

    the logging output has been updated to use the term 'agent' now. Flags,


    binaries and scripts with 'slave' keyword have been deprecated (see


    "Deprecations section below").





  * [MESOS-4312] - **Experimental** support for building and running mesos
on

    IBM PowerPC platform.





  * [MESOS-4189] - Weights for resource roles can now be configured
dynamically

    via the new '/weights' endpoint on the master.





  * [MESOS-4424] - Support for using Nvidia GPUs as a resource in the


    Mesos "unified" containerizer. This support includes running containers


    with and without filesystem isolation (i.e. running both imageless


    containers as well as containers using a docker image). Frameworks must


    opt-in to receiving GPU resources via the GPU_RESOURCES framework


    capability (see the scarce resource problem in MESOS-5377). We support


    'nvidia-docker'-style docker containers by injecting a volume that


    contains the Nvidia libraries / binaries when the docker image has


    the 'com.nvidia.volumes.needed' label. Support for the docker


    containerizer will come in a future release.





  * [MESOS-5724] - SSL certificate validation allows for additional IP
address

    subject alternative name extension verification.
