[jira] [Commented] (SPARK-17454) Add option to specify Mesos resource offer constraints

    [ https://issues.apache.org/jira/browse/SPARK-17454?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15482682#comment-15482682 ] 

Michael Gummelt commented on SPARK-17454:
-----------------------------------------

As of Spark 2.0, Mesos mode supports spark.executor.cores

And the scheduler doesn't reserve any disk.  It just writes to the local workspace.  Do you have a need for disk reservation?

> Currently the driver will accept offers from Mesos which have enough ram for the executor and until its max cores is reached. There is no way to control the required CPU's or disk for each executor, it would be very useful to be able to apply something similar to spark.mesos.constraints to resource offers instead of attributes on the offer.
