Hi, All, When I try to access sandbox on mesos UI, I see the following info( The same error appears on every slave sandbox.):
"Failed to connect to slave '20150115-144719-3205108908-5050-4552-S0' on 'centos-2.local:5051'. Potential reasons: The slave's hostname, 'centos-2.local', is not accessible from your network The slave's port, '5051', is not accessible from your network" I checked that: slave centos-2.local can be login from any machine in the cluster without password by "ssh centos-2.local "; port 5051 on slave centos-2.local could be connected from master by "telnet centos-2.local 5051" The stdout and stderr are there on each slave's /tmp/mesos/..., but seems mesos UI just could not access it. (and Both master and slaves are on the same network IP ranges). Should I open any port on slaves? Any hint what's the problem here? Cheers, Dan
