Description

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.
