             Summary: Zookeeper ZNodes for NiFi LeaderElection should use spaces for ease of use
                 Key: NIFI-3680
                 URL: https://issues.apache.org/jira/browse/NIFI-3680
             Project: Apache NiFi
          Issue Type: Improvement
    Affects Versions: 1.1.1
         Environment: Ubuntu 14, Oracle JDK 1.8.0_77, 3 Node cluster, Zookeeper 3.4.6 [2.5.3.0-37]
            Reporter: Joseph Niemiec
            Priority: Trivial


When navigating the ZKCli for problems the current naming of ZNodes for leader-election isn't easy to navigate. Noticed that the default cli behaviour of a space is that is is stored as data inside the path of the znode specified. I assume the ZK Java API is being alittle more 'powerful' but it would be nice to enable operators a easier native way to check the little things. 

```
[zk: localhost:2181(CONNECTED) 7] ls /nifi/leaders/

Primary Node          Cluster Coordinator
[zk: localhost:2181(CONNECTED) 7] ls /nifi/leaders/Primary Node
Node does not exist: /nifi/leaders/Primary
[zk: localhost:2181(CONNECTED) 8] ls /nifi/leaders/Cluster Coordinator
Node does not exist: /nifi/leaders/Cluster

[zk: localhost:2181(CONNECTED) 1] create /test blah 
Created /test
