I am in the process of learning how to run a mesos cluster with the intent for it to be the resource manager for Spark. As a small step in that direction a basic test of mesos was performed, as suggested by the Mesos Getting Started page.
In the following output we see tasks launched and resources offered on a 20 node cluster: [stack@yarnmaster-8245 build]$ ./src/examples/java/test-framework $(hostname -s):5050 I0908 18:40:10.900964 31959 sched.cpp:157] Version: 0.23.0 I0908 18:40:10.918957 32000 sched.cpp:254] New master detected at [email protected]:5050 I0908 18:40:10.921525 32000 sched.cpp:264] No credentials provided.

Is there a misconfiguration on the cluster?
