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.

Dynamic reservations without a principal

[Srikanth Viswanathan]

Hi folks,

I am trying to have the Chronos framework consume dynamic reservations in
Mesos. However, it appears that Chronos is unable to do this because it
does not pass the framework principal to Mesos when launching tasks (See
https://github.com/mesos/chronos/issues/843), which makes Mesos reject the
launch operation.

To get around this, I am considering changing my dynamic reservations to be
purely role-based instead of (role, principal)-based. Is this
allowed/valid? http://mesos.readthedocs.io/en/0.24.1/reservation/#
dynamic-reservation-since-0230 says "resources are reserved for a *role*." Does
this mean I can make a dynamic reservation just for (role) instead of
(role, principal)?

Thanks,
Srikanth

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!

Framework change role

[Thodoris Zois]

Hello list,

Is anybody available to help me with the new feature of 1.3.0 version, that a 
framework can modify its role? 

Thank you
