[GitHub] [incubator-pinot] dongxiaoman opened a new issue #6554: Zookeeper client version so zookeeper client will re-resolve hosts when IP has changed
dongxiaoman opened a new issue #6554:
URL: https://github.com/apache/incubator-pinot/issues/6554
We have the same situation as mentioned in [Zookeeper bug here](https://issues.apache.org/jira/browse/ZOOKEEPER-2184) . Simple version is, we will replace zookeeper servers with a new host that has new IP address, but still keep the host name in the DNS.
This bug in Zookeeper client is fixed in `3.4.13`+ or 3.5.5+, or 3.6.0+ and pinot is using 3.4.11
Can we upgrade at least the minor version to 3.4.13?

I'm seeing an issue of zk client connection for jdk14+ after the upgrade.
Will investigate this.
