Troubleshooting

• Check if TCP port 5050 is available.

  netstat command output

  $ netstat -lntp | grep 5050
  tcp        0      0 0.0.0.0:5050            0.0.0.0:*               LISTEN      21674/mesos-master
  

  ss command output

  $ ss -ltn | egrep 5050
  LISTEN     0      65535        *:5050                     *:*
  

  lsof command output

  $ lsof -P -n -i :5050 | grep LISTEN
  mesos-mas 21674 wfuser    6u  IPv4 74892366      0t0  TCP *:5050 (LISTEN)
  

• Check the default main log files:

  • Access logs: <INSTALL_DIR>/supervisord/log/mesos-master.out.log
  • Error logs: <INSTALL_DIR>/supervisord/log/mesos-master.err.log

  $ tail -f <INSTALL_DIR>/supervisord/log/mesos-master.err.log <INSTALL_DIR>/supervisord/log/mesos-master.out.log
  

• Check the mesos-master out (access) log using the wfmanager util:

  wfmanager tail mesos-master
  

• Enable more detailed debug information.

  Set the debug log level to <INSTALL_DIR>/supervisord/apps/mesos-master.ini and restart the mesos-master service:

  ${install_dir}/supervisord/apps/mesos-master.ini

  Add the following to the start-up configuration part of this file:
  --enable-debug    
  

  wfmanager restart mesos-master
