Hi Alex,
>>Granularity in the allocator is a single agent.
Does this mean if I have only one agent and the moment if I set any quota, the
framework running on the agent will not be allocated with any resource?

Granularity in the allocator is a single agent. Hence even though you set
quota for 0.0001 CPU, at least one agent is "blocked". This is probably the
reason why marathon is not getting offers. You can turn verbose master logs and
check allocator messages to confirm. Alex.
