Hi, I am hoping someone can shed some light on this.
An agent node failed to start, that is, when I did "service mesos-slave start" the service came up briefly & then stopped. Before stopping it produced the log shown below. The last thing it wrote is "Trying to create path '/mesos' in Zookeeper". This mention of the mesos znode prompted me to go for a clean slate by removing the mesos znode from Zookeeper. After doing this, the mesos-slave service started perfectly. What might be happening here, and also what's the right way to trouble-shoot such a problem? Mesos is version 0.23.0. Thanks for your help. -Paul Log file created at: 2016/03/29 14:19:39 Running on machine: 71.100.202.193 Log line format: [IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line] msg I0329 14:19:39.512249 5870 logging.cpp:172] INFO level logging started!
