             Summary: Wait for CuratorFramework connection to be established
                 Key: FLINK-4117
                 URL: https://issues.apache.org/jira/browse/FLINK-4117
             Project: Flink
          Issue Type: Bug
          Components: State Backends, Checkpointing
    Affects Versions: 1.1.0
            Reporter: Greg Hogan


Received the following error when locally running {{mvn verify}}. Searching on the error it looks like we are not waiting for the Zookeeper connection to be established as this occurs asynchronously. In ZookeeperUtils.java:98 we call {{CuratorFramework.start()}} and we could then call {{{{CuratorFramework.blockUntilConnected}} with the same timeout.
