Subject [jira] [Commented] (MESOS-312) Mesos never makes offers with only cpus
Date Fri, 16 Nov 2012 19:02:13 GMT


Benjamin Mahler commented on MESOS-312:

Looks like we only offer when there's more than 1 cpu and more than 32MB of memory available.

Seems like both can be problematic, we should revisit this logic and these constants.

> If a framework already has an executor placed on a machine, it may be able to use an
offer that contains no or almost no memory but includes cpus. The current allocator will never
make such offers. 
> This can lead to non-intuitive results: If one runs Spark against Mesos configuring Spark
to use almost exactly the available-to-Mesos memory, Spark will start running but eventually
