Anand Mazumdar updated MESOS-6034:
----------------------------------
Description:
Use case:
We have local daemons at every machine in the cluster. They often need to know
what tasks is running at the local host and perform operations.
Right now they can only poll `/state` endpoint or operator API. Let them able
to subscribe task changes on the agent seems a good improvement.
The only way to be actively notified otherwise is to implement part of all
logic as a hook, but doing this directly in agent is better and easier for
everyone.
For MVP, something similar to current master API's `TASK_ADDED` and
`TASK_STATUS` seems a pretty good starter.
