marathon rest api returns no data

Question

I have 3 marathon servers running in HA. when i reach the rest api on the leader, it returns good data. But when i try it against one of the non leader nodes, I do not get any data back...no strings at all. The headers say 200...but no data. Has anybody experienced this before?

here is what i see on the leader

# curl -i http://10.0.0.1:8080/v2/apps
HTTP/1.1 200 OK
X-Marathon-Leader: http://x1-master-0:8080
Cache-Control: no-cache, no-store, must-revalidate
Pragma: no-cache
Expires: 0
Content-Type: application/json; qs=2
Connection: close
Server: Jetty(8.y.z-SNAPSHOT)

{"apps":[]}

here is the data from the non leader

# curl -i http://10.0.0.2:8080/v2/apps
HTTP/1.1 200 OK
Connection: close
Server: Jetty(8.y.z-SNAPSHOT)

Also, what does `curl -i http://x1-master-0:8080/v2/apps` give you from the host on which the queried non-leader Marathon instance is running? — Michael Hausenblas, Sep 21 '15 at 13:28
Thanks Michael, that was it. marathon version is 0.10.1. the other marathon servers could not resolve the leader by name...adding to /etc/hosts on the other servers made them reply with data. — suppandi g, Sep 21 '15 at 14:27
Cool. I suggest you answer yourself, below (that is, describe the solution) for future reference and that others benefit from it. — Michael Hausenblas, Sep 21 '15 at 15:17

the problem was that the marathon servers could not resolve each other by name. Adding the hostnames of the other marathon servers to each marathon's /etc/hosts file fixed the problem.
