Vinod Kone updated MESOS-7887:
------------------------------
Priority: Minor (was: Critical)
> `GET_EXECUTORS` and `/state` is not consistent between master and agent
> -----------------------------------------------------------------------
>
> Key: MESOS-7887
> URL: https://issues.apache.org/jira/browse/MESOS-7887
> Project: Mesos
> Issue Type: Improvement
> Components: HTTP API, master
> Affects Versions: 1.3.0, 1.5.0
> Reporter: Alexander Rojas
> Priority: Minor
> Labels: master, mesosphere, v1_api
>
> 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=${MASTER_IP}:5050 \
>
> --task='{"name":"test-custom-command","task_id":{"value":"test-custom-command-task-1"},"agent_id":{"value":"50f4e551-aa5c-42db-8967-4dc3ee11658f-S0"},"resources":[{"name":"cpus","type":"SCALAR","scalar":{"value":1}},{"name":"mem","type":"SCALAR","scalar":{"value":32}},{"name":"disk","type":"SCALAR","scalar":{"value":32}}],"executor":{"executor_id":{"value":"test-custom-command-executor"},"command":{"value":"while
> true; do echo \"Hello World\"; sleep 5; done;"}}}'
> {noformat}
> {noformat}
> ./src/mesos-execute \
> --master=${MASTER_IP}:5050 \
> --name=test-command \
> --command='while true; do echo "Hello World"; sleep 5; done;' \
> --containerizer=docker \
> --docker_image=ubuntu:latest
> {noformat}
> Not using the operator endpoints on the agent:
> {noformat}
> $ http POST ${AGENT_IP}:5051/api/v1 type=GET_EXECUTORS

> {noformat}
> 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.
