Description

Attempting to specify resources file via --resources=/etc/mesos-slave/small-slave-config.json threw the following error:

Failed to determine slave resources: Bad value for resources, missing or extra ':' in /etc/mesos-slave/small-slave-config.json

I confirmed I had valid JSON:

[
{
"name": "cpus",
"type": "SCALAR",
"scalar":

{ "value": 0.5 }

},
{
"name": "mem",
"type": "SCALAR",
"scalar":

{ "value": 512 }

}
]

In actuality, I misread to docs with my file pattern. Once I changed to resources=file:///etc/mesos-slave/small-slave-config.json the mesos slave started up fine. Just need a missing file check and corresponding error message to fix this.
