> 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:
> ERROR org.apache.curator.framework.imps.CuratorFrameworkImpl - Background exception was not retry-able or retry gave up
