【原创】大叔经验分享（101）marathon反复重启

marathon反复重启

# systemctl status marathon
● marathon.service - Marathon
   Loaded: loaded (/usr/lib/systemd/system/marathon.service; enabled; vendor preset: disabled)

  Process: 9910 ExecStartPre=/bin/mkdir -p /run/marathon (code=exited, status=0/SUCCESS)

通过journalctl查看日志如下：

检查mesos发现mesos异常，最终定位原因为zookeeper节点之间数据不同步，mesos在zookeeper上维护master leader信息

[zk: 192.168.0.1:2181(CONNECTED) 1] ls /mesos

[json.info_0000000114, log_replicas, json.info_0000000115]

这个数据不同步导致mesos找不到master，进而导致marathon异常，将有问题的zookeeper节点stop，清空数据目录后重启，数据一致后问题解决；
