Description

When I tried to deploy an application on mesos-agent(windows), the moment application is deployed mesos agent service on windows node is crashed and in logs I can see error:
I0714 07:20:09.788785 5640 containerizer.cpp:781] Starting container '031878d5-32fa-41ed-8b23-d0d91fe34f05' for executor 'windemo.10cc3e54-49ce-11e6-a2a2-08002786cbbf' of framework '5c83c39f-75a0-4f38-9e47-633767b47976-0000'

We debug the issue and found issue with fine name reached to max filepath length: E:\agentlogs\meta\slaves\803264d5-8f2d-46bb-8019-de0f9565c971-S5\frameworks\5c83c39f-75a0-4f38-9e47-633767b47976-0000\executors\windemo.10cc3e54-49ce-11e6-a2a2-08002786cbbf\runs\031878d5-32fa-41ed-8b23-d0d91fe34f05\tasks\windemo.10cc3e54-49ce-11e6-a2a2-08002786cbbf

I think path length limit in windows is 256 which is revoked and this made service to be crashed while this will work fine for linux mesos agents so we may have to control current UUID.toString() method to be shorter
