Klaus Ma updated MESOS-3892:
----------------------------
Description:
The Mesos master already keeps track of all executors running on a given agent.
We may wish to add a helper to retrieve the evictable executors:
* The evictable executor will hash by role; only Lender Framework/Role can
reclaim its resources back
* The RevocableInfo::type of executor & task must be consistent (MESOS-XXXX)
{noformat}
class Slave {
...
// How the master currently keeps track of executors.
hashmap<FrameworkID, hashmap<ExecutorID, ExecutorInfo>> executors;
...
// Returns the list of executors that are using optimistically-
// offered, revocable resources.
list<ExecutorID> getEvictableExecutors() { ... }
...
}
{noformat}
