I have installed DCOS with one agent and 3 masters and tried installing ArangoDB but it is failing to deploy arangodb.
Below is the config seen as per the log.

And below is the error seen in the log file.

I believe one agent server is also sufficient. Is it that number of the agents should also be 3 servers ?
Also need to know how to restart the entire cluster and single service if need be ? (Killing processes doesn't seem to be right way)
Can someone suggest what exactly needs to done here...
Thanks in advance!
