> We use curator for leader election within our 2 clients, sometimes none of the 2 clients
was a leader.
> We checked the log and found this caused by a exception which was being throwed in method
LeaderLatch.checkLeadership(), after throwing this exception the curator won't do the leader
election. Here is error log:
