Klaus Ma commented on MESOS-3372:
---------------------------------
Why not use slave's attributes when launch tasks?
{code}
...
repeated Resource resources = 5;
repeated Attribute attributes = 7;
repeated ExecutorID executor_ids = 6;
...
{code}
> Allow mesos agent attributes to be tokenized in taskInfo

> Project: Mesos
> Issue Type: Improvement
> Reporter: Chad Heuschober
>
> Some applications workloads would benefit from having access to the
> statically defined slave attributes. By processing `taskInfo` on the slave
> such tokens, as defined in `taskInfo` could be replaced with the appropriate
> values to achieve such objectives as rack locality.
> Example:
> Before token replacement:
> {code}
> {
> "discovery": {
> "environment": "RACK_@MESOS.AGENT.ATTRS.RACK_ID@"
> }
> }
> {code}
> After token replacement:
> {code}
> {
> "discovery": {
> "environment": "RACK_DC131R57"
> }
> }
> {code}
