[jira] [Resolved] (FLINK-4117) Wait for CuratorFramework connection
to be established

Greg Hogan resolved FLINK-4117.
-------------------------------
Resolution: Cannot Reproduce
> 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.
