Task properties/attributes?

[James Vanns <jv...@gmail.com>]

Does a mesos task feature a URI attribute or list thereof? For downloading
data automatically within the sandbox in which the command will execute?
Eg. upon defining a task I wish to supply a list of
sources from which to download various different types of data all destined
for the container that the task executes in -- the command will then
process this data, upload any result and the downloaded data is discarded
on task completion (when the container/sandbox is destroyed).

I can't find anything that suggests this is possible in the online
documentation - but I thought I read it some where!?

Cheers,

Jim

You can specify the URIs to download when you launch the actual process
(either with your custom executor, or a Command executor. The URIs to be
downloaded are set here:
https://github.com/apache/mesos/blob/master/include/mesos/mesos.proto#L234

It doesn't look like there's a way to do this when you send additional
tasks to a preexisting executor.
