Description

The libraries (used by scheduler and executor) should expose their version on an endpoint.

stats exposed by the scheduler driver

# netstat -dnatp | grep LISTEN | grep java 
tcp        0      0 0.0.0.0:48747               0.0.0.0:*                   LISTEN      1699/java           
tcp        0      0 :::8081                     :::*                        LISTEN      1699/java           
# curl -s http://localhost:48747/metrics/snapshot | python2.7 -m json.tool
{
    "scheduler/event_queue_messages": 0,
    "system/cpus_total": 24,
    "system/load_15min": 0.18,
    "system/load_1min": 0.29,
    "system/load_5min": 0.2,
    "system/mem_free_bytes": 7850483712,
    "system/mem_total_bytes": 33534873600
}

Likewise, for the master and slave, a lightweight endpoint is desired, see MESOS-2644 as well.
