Hi, I’d like to upgrade zookeeper in hbase (and in other components as well) to 3.8.1 version and curator to 5.4.0 version. It is useful since the current zookeeper version 3.5.7 is EOL and we should release HBASE 3 with the latest zookeeper to be on an active version. ZooKeeper clients from 3.5.x onwards are fully compatible with 3.8.x servers. ZooKeeper 3.8.x clients are compatible with 3.5.x, 3.6.x and 3.7.x servers as long as we are not using new APIs not present these versions. See ZooKeeper 3.8.0 Release Notes[1] for details. Curator 5.0 contains a few non-backward compatible/breaking changes from previous versions: https://curator.apache.org/breaking-changes.html, but these changes have no effect on hbase. See Curator Release Notes[2] for details. Do you have any suggestions?
