When I submitted WordCountTopology to the Heron Cluster that deployed with Aurora scheduler and Zookeeper, this error happened as follows：
yitian@heron01:~$ heron submit aurora/yitian/devel --config-path ~/.heron/conf ~/.heron/examples/heron-api-examples.jar com.twitter.heron.examples.api.WordCountTopology WordCountTopology --deploy-deactivated

What's wrong with it? Thanks for your help.
From the logs:

Heron is able to connect to ZK and check node successfully, so ZK cluster seems to be running and readable. However it seems that for some reason curator failed to create the node in ZK: /heron/topologies/WordCountTopology
Heron topology keeps its running data in ZK so it cant start if it failed to create the key nodes. You need to find out the cause for the ZK failure (permission?) and solve it.
