Niklas Quarfot Nielsen commented on MESOS-1384:
-----------------------------------------------
Thanks Bernd - that's one point I didn't touch base on; How do we describe the
library paths to use on start-up?
For example, in the case of isolator modules we want to be able to start with
flags like --isolation="cgroups/cpu,module/foobar" where libfoobar.so is
located in the default library location. Is that the right way to think about
it? What do we do when users want to define absolute paths to libraries
instead? Maybe --isolation="..., module/path/to/libfoobar.so" or
module:///path/to/libfoobar.so?
It is a bit easier to argue about for something like allocator modules, where
the --allocator="foobar" or --allocator="/path/to/libfoobar.so"
Would love to get some input here.
> Add support for loadable MesosModule

> Key: MESOS-1384
> URL: https://issues.apache.org/jira/browse/MESOS-1384
> Project: Mesos
> Issue Type: Improvement
> Affects Versions: 0.19.0
> Reporter: Timothy St. Clair
> Assignee: Niklas Quarfot Nielsen
>
> I think we should break this into multiple phases.
> -(1) Let's get the dynamic library loading via a "stout-ified" version of
> https://github.com/timothysc/tests/blob/master/plugin_modules/DynamicLibrary.h.
> -
> *DONE*
> (2) Use (1) to instantiate some classes in Mesos (like an Authenticator
> and/or isolator) from a dynamic library. This will give us some more
> experience with how we want to name the underlying library symbol, how we
> want to specify flags for finding the library, what types of validation we
> want when loading a library.
> *TARGET*
> (3) After doing (2) for one or two classes in Mesos I think we can formalize
> the approach in a "mesos-ified" version of
> https://github.com/timothysc/tests/blob/master/plugin_modules/MesosModule.h.
> *NEXT*
