Re: Threading model of mesos API (C++)

Thanks for the responses, guys. That link of the 'detailed description' will be handy - I've not come across that before. I do now have another question though! Aren't these two a contradiction; Alex; you launch a task, before the method returns (say you do some blocking stuff after, like sync

Re: Threading model of mesos API (C++)

Jim, Let me prototype something small today. After reading my scheduler (in c++) i do have comments and synchronization on some state vars, but it might have to do with a more complex async code base I manage. I'll get back to you. - alex On Wed, Jun 10, 2015 at 6:15 AM, James Vanns

Re: Can Mesos master offer resources to multiple frameworks simultaneously?

I'll try to answer these questions. 1. Currently, the only language you can use is C++. You can workaround this by writing a proxy in c++ that delegates the calls to, say, python scripts. See http://mesos.apache.org/documentation/latest/allocation-module/ for more details. 2. The default

Debugging framework registration from inside docker

Hi. When attempting to run my scheduler inside a docker container in --net=bridge mode it never receives acknowledgement or a reply to that request. However, it works fine in --net=host mode. It does not listen on any port as a service so does not expose any. The scheduler receives the mesos

Re: Can Mesos master offer resources to multiple frameworks simultaneously?

Thanks Alex. For 1. I understand currently the only choice is C++. However, as Adam mentioned, true pluggable allocator modules (MESOS-2160 https://issues.apache.org/jira/browse/MESOS-2160) are landing in Mesos 0.23, so at that time, I assume we will have more choices, right? For 2 and 3, my
