Hi all,
Please vote on releasing the following candidate as Apache Mesos 1.0.0.
*The vote is open until Tue Jul 25 11:00:00 PDT 2016 and passes if a
majority of at least 3 +1 PMC votes are cast.*
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
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
* [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.
