> Include server.#=... and/or a myid file when running standalone, zk server will crash with
> java.lang.NullPointerException
>    at org.apache.zookeeper.server.quorum.FastLeaderElection.totalOrderPredicate(FastLeaderElection.java:466)
>    at org.apache.zookeeper.server.quorum.FastLeaderElection.lookForLeader(FastLeaderElection.java:635)
>    at org.apache.zookeeper.server.quorum.QuorumPeer.run(QuorumPeer.java:515)
> Seen when running zk embedded in other server, using
> String[] args = new String[]{zookeeperCfgFile};
> org.apache.zookeeper.server.quorum.QuorumPeerMain.main(args);
> The workaround is of course to fix the config, but 3.1.1 managed to not crash on this.
