> There are a few components to this.
> 1) The Framework: This is going to be responsible for starting up and
> managing the fail over of brokers within the mesos cluster. This will have
> to get some Kafka focused paramaters for launching new replica brokers,
> moving topics and partitions around based on what is happening in the grid
> through time.
> 2) The Scheduler: This is what is going to ask for resources for Kafka
> brokers (new ones, replacement ones, commissioned ones) and other operations
> such as stopping tasks (decommissioning brokers). I think this should also
> expose a user interface (or at least a rest api) for producers and consumers
> so we can have producers and consumers run inside of the mesos cluster if
> folks want (just add the jar)
> 3) The Executor : This is the task launcher. It launches tasks kills them
> off.
> 4) Sharing data between Scheduler and Executor: I looked at the a few
> implementations of this. I like parts of the Storm implementation but think
> using the environment variable
> ExectorInfo.CommandInfo.Enviornment.Variables[] is the best shot. We can
> have a command line bin/kafka-mesos-scheduler-start.sh that would build the
> contrib project if not already built and support conf/server.properties to
> start.
> The Framework and operating Scheduler would run in on an administrative node.
> I am probably going to hook Apache Curator into it so it can do it's own
> failure to a another follower. Running more than 2 should be sufficient as
> long as it can bring back it's state (e.g. from zk). I think we can add this
> in after once everything is working.
