Hi, @Aaron Sorry the incorrect conclusion about executor in Marathon, Chronos. According this link http://stackoverflow.com/questions/17466204/scheduling-a-custom-mesos-executor-with-airbnb-chronos-rest-api and this link https://github.com/mesosphere/marathon/blob/master/src/test/scala/mesosphere/mesos/TaskBuilderTest.scala#L247-L251 The answer of " making the executor file executable, putting it on the slave, and supplying the path to it in the JSON" is yes.

The data required by each task is specified in our database. Basically I wanted to customise an executor to prepare the data on the slave before executing the docker container, rather than having to get the container to download its own data or attempt to mount NFS volumes itself. I hope that all makes sense, I couldn't find a simple solution to this using the existing architecture.. I'd love to know your thoughts though!

I want to be able to write a custom executor which is available to multiple schedulers (eg Marathon, Chronos and our own custom scheduler). Is this possible? I couldn't quite figure out the best way to go about this from the docs? Is it possible to mix and match languages for schedulers and executors? (ie one is python one is C++) Thanks, Aaron -- Best Regards, Haosdent Huang
