Re: Framework change role

[Gabriel Hartmann]

You may register in multiple roles simultaneously.  Register with the
MULTI_ROLE capability (
https://github.com/apache/mesos/blob/master/include/mesos/mesos.proto#L345).
Our frameworks all register with a role, but never the role '*'.  We get
Offers from all agents that don't have statically partitioned resources and
do dynamic reservation into one of our registered roles.  I don't know the
purpose or goals of your project, but some example Java based frameworks
are available here: https://github.com/mesosphere/dcos-commons.

We use multiple roles when appropriate here:
https://github.com/mesosphere/dcos-commons/blob/master/sdk/scheduler/src/main/java/com/mesosphere/sdk/specification/DefaultService.java#L200

Maybe have a look at the DefaultScheduler for an implementation of a look
at the DefaultScheduler there as well, if you're just trying to get things
building and off the ground (
https://github.com/mesosphere/dcos-commons/blob/master/sdk/scheduler/src/main/java/com/mesosphere/sdk/scheduler/DefaultScheduler.java#L53
).

Note that you can start multiple Scheduler drivers within the same server. Each 
one can register with Mesos as a separate framework.

If you start multiple Scheduler drivers, they can all share a TreeMap because 
they are running in the same Java process.

Re: Framework change role

[Thodoris Zois]

Ok, probably you are right but what you don’t understand is that i am a 
completely newbie and i see such systems for the first time. It’s about a 
university project that i am working on in order to get my bachelor degree. I 
don’t really know the proper way to express what i want to like you do. I don’t 
know how to connect 2 frameworks or something, i don’t even know how to make my 
own framework and compile it with the dependencies that Mesos needs. I am just 
writting on TestFramework.java and TestExecutor.java and that’s all. The reason 
that i want to run everything from the same framework (instance) is because 
keep a TreeMap with some info that i don’t want to lose if i terminate the 
Schedulers driver. So if i start up a new framework, TreeMap is gone. Forget 
about the tasks, i can use the same TestExecutor.java for every scheduler. 

What i want to achieve is to get offers from a specific agent with role “SB” 
and run 10 tasks (i give also to my Framework role “SB”), then i store those 
information (which are actually TaskInfo in Schedulers TreeMap). After that i 
would like to change the role of my Framework to “*(default)”. Then i will get 
offer from an agent that has the default role and i will still have the info in 
my TreeMap because scheduler instance didn’t stop.

That’s all. My problem is that i don’t know how to change the role of the 
Framework without losing that TreeMap, and also how to set it with version 
1.3.0.  

Hope that everybody understands now….
Thank you, and i am really sorry for the spam

As I suggested on Slack, I still think the most obvious way to implement this 
is to connect 2 frameworks, 1 for each role. Just co-ordinate internally to 
accept the offers you want in the right sequence. From your description, 
there's no requirement for this to be done in 1 framework.

I don't really follow what you mean by "run the same tasks". You can run new 
instances of the same task (from whatever framework you like); you can also 
send new tasks to an existing executor (from the same framework).

I think that for people to help you, they need to be able to understand the

Re: Framework change role

[Thodoris Zois]

Hi, 

No, i would like my framework to be offered resources from agent with role 
(e.g: thz) and after running the specific tasks change its role to (*) in order 
to get offers from different agents, but it will run the same tasks because i 
am never terminating the scheduler driver (that’s what i want to). Don’t try to 
find logic, it’s not for a company or something :)

Thank you,
Thodoris

Re: Framework change role

[Jay Guo]

Hi Thodoris,

If I understand correctly, you would like your framework to receive offers
from both 'role' and '*', so resources reserved to 'role' on particular
agent could be reliably supplied to the framework? Isn't it sufficient to
start your framework with multiple roles, 'role' & '*'? You need to enable
the capability.

Re: Framework change role

[Thodoris Zois]

I have built a Framework in Java that is running certain tasks. I would like to 
run those tasks on a specific agent. I have set a role to the Framework and 
used flags upon starting of the agent. Till here everything is good. When 
framework has run tasks successfully i am not terminating it. I would like to 
change its role to default (*) and get offered resources from master that 
correspond to that role and it will run again the same amount of tasks (and the 
same tasks) because i never terminated (and i don't want to terminate its 
instance because i keep some mesos metrics to a static TreeMap). That's all.. I 
just wanted somebody to explain me exactly how it works and what i have to do 
because everything i have tried today fails, and seems i can't find useful info 
on the Internet about this. 

Thank you!
