             Summary: Allow http endpoint to dynamically change the slave attributes
                 Key: MESOS-3059
                 URL: https://issues.apache.org/jira/browse/MESOS-3059
             Project: Mesos
          Issue Type: Wish
            Reporter: Nitin


This is well understood that - changing the attributes dynamically is not safe without a restart because slave itself may not know which old framework tasks are running on it that were dependent on previous attributes. 

However, total restart makes lot of other history to delete. We need to ensure a dynamic attribute changes with a soft restart. 

It will be good to expose a rest endpoint either at slave or mesos-master which directly changes the state in zookeeper.

USE-CASE
We use slave attributes/roles to direct the framework scheduling to use specific slave as per it's requirements. Mesos scheduler only creates the offer on the basis of some resources.
In our use case, we have some categorization of our spark frameworks or jobs with framework(like marathon) based on multiple factors. We want job or frameworks belonging to one category be running into their specific cluster of resources. We want to dynamically manage the slaves into these logical sub-clusters.
