Klaus Ma updated MESOS-3892:
----------------------------
Description:
In the agent, add a helper function to get the list of the exeuctor using
ALLOCATION_SLACK.
It's short term solution which is different the design document, because master
did not have executor for command line executor. Send evicatble executors from
master to slave will addess in post-MVP after MESOS-1718.
{noformat}
class Slave {
...
// If the executor used revocable resources, add it into `evictableExecutors`
// list.
void addEvictableExecutor(Executor* executor);
// If the executor used revocable resources, remove it from
// `evictableExecutors` list.
void removeEvictableExecutor(Executor* executor);
// Get evictable executor ID list by `Resource::RevocableInfo::Type`.
std::list<ExecutorID> getEvictableExecutors(
Resource::RevocableInfo::Type type);
...
// The map of evictable executor list. If there's not enough resources,
// the evictable executor will be terminated by slave to release resources.
hashmap<mesos::Resource::RevocableInfo::Type, std::list<ExecutorID>>
evictableExecutors;
...
}

was:

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-
