> --------------------------------------------------

> Key: CURATOR-519
> URL: https://issues.apache.org/jira/browse/CURATOR-519
> Project: Apache Curator
> Issue Type: Wish
> Components: General
> Affects Versions: 4.0.1, 4.1.0
> Reporter: Raúl Gracia Tinedo
> Priority: Major
> Labels: easyfix
> Time Spent: 10m
> Remaining Estimate: 0h

> We are using Curator 4.0.1 in our project (Pravega, [https://github.com/pravega/pravega]).
> Just for context, we are intensively deploying Pravega on Kubernetes. In this sense, Zookeeper (3.5.4-beta) is also being deployed as a service in Kubernetes. In this environment, Zookeeper instances (i.e., pods) can be frequently restarted or relocated and their IP may change. Properly handling this situation requires to re-resolve the IP for hostname of Zookeeper instances.
> In fact, we are experiencing problems with this exact issue with Curator 4.0.1 (i.e., re-resolution of Zookeeper hostnames), which internally uses Zookeeper 3.5.3-beta as a dependency. Details can be found in this GitHub issue: [https://github.com/pravega/pravega/issues/3651]
>
> Fortunately, the proper resolution of Zookeepr hostnames has been actually reported and fixed in the Zookeeper project:
> - Issue: https://issues.apache.org/jira/browse/ZOOKEEPER-2184
> - Commit on Zookeeper 3.5.5 branch: [https://github.com/apache/zookeeper/commit/1e65b9f4873fc995308972433ea8a664e98fe41f]
>
> To verify that it helps us to solve our problem, I have built a custom Curator 4.0.1 library using Zookeeper 3.5.5 and then I used that library to build a Pravega image. A couple of comments to take into account:
> - Using Zookeeper 3.5.5 to build Curator 4.0.1 required no code change, just changing the Zookeeper dependency version in the pom.xml (I had the same experience with Curator 4.1.0).
> - I verified that using Curator 4.0.1 and 4.1.0 with Zookeeper 3.5.5 solves the re-resolution of Zookeeper hostnames, which makes our system able to properly handle Zookeeper instance restarts.
>
> Therefore, the main point of this issue is: _is in the roadmap to release Curator 4.0.x and/or 4.1.x using Zookeeper 3.5.5?_ (Note that Zookeeper 3.5.5 is about to get released: [https://github.com/apache/zookeeper/releases])
>
> Thanks in advance,
> Raúl.
