### Fixed

- Fix Zookeeper hbase.rootdir when users point to discovery ConfigMap of ZookeeperCluster rather than ZNode. Print a warning in that case ([#394]).
- Default `hbase.unsafe.regionserver.hostname.disable.master.reversedns` to
`true`, to ensure the names of RegionServers are resolved to their hostnames
instead of IP addresses ([#418]).

### Removed
