I have a problem where we are trying to run several services on our mesos dcos cluster and some are running spark process and some python services. So in our small test mesos dcos cluster we reach 70% cpus resources used multiple times per day.
And services people want to start just get hanging waiting for cpu offers that can be well met on slave nodes but for some reson are not allowed to be allocated.
A typical example would be 7 total cpus unused and 1-3 services looking for cpu offers of 0.5 to 2 cpu resources to use. that can be met. if looking on the node resource over view.
To my question are there a hard limit not allowing more then 70% of the cpus to be allocated at the same time?
And are there a reson for this limit what would be the effect of changing this to a higher value?
And last who do we change the limit?
