Till Rohrmann commented on FLINK-15241:
---------------------------------------

Thanks for reporting this issue [~karmagyz]. I've assigned you to the ticket. 
It would be good to align how Mesos obtains the number of cpus with FLINK-14188 
and to use {{TaskExecutorResourceUtils#getCpuCores}}. Let me know once you've 
opened a PR so that I can review it.

> Before 1.10, the default config of cpu cores for Mesos Workers is equal to 
> taskmanager.numberOfTaskSlots. However, it is now 0.0 by default. I feel 
> sorry I've not catch it in 
> [FLINK-15196|https://issues.apache.org/jira/browse/FLINK-15196]. I think this
