> The master seem not to keep information about the executors since they are not returned
either either by getting the master state (with either v0 and v1 API's) or with the call {{GET_EXECUTORS}}.
Creating a cluster as follows:
> {noformat}
> ./bin/mesos-master.sh \
>     --ip=${MASTER_IP} \
>     --work_dir=/tmp/mesos/master \
>     --log_dir=/tmp/mesos/master/log
> {noformat}
> {noformat}
> sudo ./bin/mesos-agent.sh \
>     --master=${MASTER_IP}:5050 \
>     --work_dir=/tmp/mesos/agent \
>     --log_dir=/tmp/mesos/agent/log \
>     --containerizers=mesos,docker
> {noformat}
> And launch  a couple of frameworks as follows:
> {noformat}
> ./src/mesos-execute \
>     --master=${MASTER_IP}:5050 \
>     --task='{"name":"test-custom-command","task_id":{"value":"test-custom-command-task-1"},"agent_id":{"value":"50f4e551-aa5c-42db-8967-4dc3ee11658f-S0"},"resources":[{"name":"cpus","type":"SCALAR","scalar":{"value":1}},{"name":"mem","type":"SCALAR","scalar":{"value":32}},{"name":"disk","type":"SCALAR","scalar":{"value":32}}],"executor":{"executor_id":{"value":"test-custom-command-executor"},"command":{"value":"while

> These results are consistent using the `/state` endpoint on both, agent and master as
well as using the {{GET_STATE}} v1 API call. The agent returns information about executors,
while the master response has none.
