Hello Markus,

I had a similar question (http://mail-archives.apache.org/mod_mbox/incubator-spark-user/201310.mbox/%3CC6960B654043804182DF9FD46E83E6DF13F8E6CE%40CWYIGMBCRP01.Corp.Acxiom.net%3E
) a few days ago. You can exclude small memory footprint mesos nodes by specifying the executor
memory as being pretty high. But I agree with what you're trying to do. Being able to handle
heterogeneous clusters would be a very handy feature to add to Spark. Ex: smart job creation
per mesos node appropriate for that node's resources. 

Regards,
Charles

Subject: Spark in a heterogeneous computing environment

Hi

Is it currently possible to define in Spark that some worker node should be preferred to the
other worker nodes? That is, in a heterogeneous computing environment some computing units
can be more powerful than the others and assigning computing jobs to them should be prioritized.

Best regards,
Markus Losoi (markus.losoi@gmail.com)
