Hi, @caogaoin. I try in with the master branch of Mesos and Marathon. And
it works fine for me.
```

```
Let me list my verify steps to help you find your problem when start your
tasks.
1. start Mesos master and agent, and reserve resources for dev.
```
$ ./bin/mesos-master.sh --work_dir=/tmp/mesos --ip=127.0.0.1
--hostname=127.0.0.1
$ ./bin/mesos-slave.sh --work_dir=/tmp/mesos --ip=127.0.0.1
--hostname=127.0.0.1 --master=127.0.0.1:5050
$ curl -i -d slaveId=dda04940-55b6-4ba7-a7bb-75c2108f3151-S0 \
-d resources='[
{
"name": "cpus",
"type": "SCALAR",
"scalar": {
"value": 2.0
},
"role": "dev",
"reservation": {
}
},
{
"name": "mem",
"type": "SCALAR",
"scalar": {
"value": 1024.0
},
"role": "dev",
"reservation": {
}
}
]' -X POST http://127.0.0.1:5050/reserve
2. start Marathon with dev role
```
./bin/start --master 127.0.0.1:5050 --zk zk://10.10.120.61:2181/marathon
--mesos_role dev
```
3. start task
```
$ cat task.json
{
"id": "/test-health",
"cmd": "sleep 200",
"cpus": 1.0,
"mem": 128.0
}
$ curl -X POST -H "Content-type: application/json"
http://127.0.0.1:8080/v2/apps -d @task.json
```
