For frameworks that need custom functionality to run tasks, a `CUSTOM` executor can be used.

Mesos provides a simple built-in default executor that frameworks can leverage to run shell commands and containers.

Indicates whether the framework is aware of GPU resources.

This expresses the ability for the framework to be "multi-tenant" via using the newly introduced `roles` field, and examining `Offer.allocation_info` to determine which role the offers are being made to.

Indicates that (1) the framework is prepared to handle the following TaskStates: TASK_UNREACHABLE, TASK_DROPPED, TASK_GONE, TASK_GONE_BY_OPERATOR, and TASK_UNKNOWN, and (2) the framework will assume responsibility for managing partitioned tasks that reregister with the master.

Indicates that the framework is prepared to receive offers for agents whose region is different from the master's region.

EXPERIMENTAL.

In this mode, a machine is not running any tasks and will not offer any of its resources.

In this mode, all agents on the machine are expected to cooperate with frameworks to drain resources.

In this mode, a machine is behaving normally; offering resources, executing tasks, etc.

The master can drain or deactivate agents when requested via operator APIs.

The master can handle slaves whose state changes after reregistering.

The master can handle the new quota API, which supports setting limits separately from guarantees (introduced in Mesos 1.9).

The volume in a container will receive new mounts from the host or other containers, and its own mounts will be propagated from the container to the host or other containers.

The volume in a container will receive new mounts from the host or other containers, but filesystems mounted inside the container won't be propagated to the host or other containers.
