Clément Michaud commented on MESOS-9315:
----------------------------------------
Hello Benjamin,
I've done the patch for this feature:
[https://reviews.apache.org/r/69938/.|https://reviews.apache.org/r/69938/]
I had another use case for it lately: I tried to run Spark on our Mesos cluster
and since we installed the XFS isolator with hard limit enforced, every task
should have a given amount of disk. However, there is currently no way to
allocate disk to a Spark executor. I'm patching the framework to introduce it
but in the meantime this review should temporarily solve this issue if we put
let say 5GB of disk by default for every tasks that do not reserve any amount
like Spark.
Best regards,
Clément

>
> I sent a an email (attached) few days ago to propose the introduction of a
> new hook to append resources implicitly to tasks for mandatory resources.
> This would allow Mesos to support mandatory resources like network bandwidth
> or disk IO for instance.
> In a nutshell, we propose to add a hook with the following signature
> {code:java}
> Result<Resources> masterLaunchTaskResourceDecorator(
> const Resources& slaveResources,
> TaskInfo& task)
> {code}
> and call it in the master in the ACCEPT message handler.
