Resolution: Cannot Reproduce
Affects Version/s: 0.23.0
Fix Version/s: None
CentOS 7.1, 3 Node cluster, each host has mesos master/slave and zookeeper setup.
After I pushed out a bad zoo.cfg (added 2 extra zookeeper hosts that didn't exist) about every three minutes the elected master restarts and this keeps happening, when I have just one of the three masters running, it restarts every 3 minutes.
I fixed the configs, deleted all the files under (/var/log/zookeeper/version-2/, /var/lib/zookeeper/version-2/). Is there another step I need to take, I feel like zookeeper is the issue (also where I lack knowledge), this cluster was stable for months until I push out the bad zoo.cfg.
The master logs have this output every second:
