It's always a good idea to share the HDP and Zk version plus the zk logs in /var/log/* having said that can you share your zoo.cfg ?
If you really need enable all four letter word commands by default, you can use the asterisk option so you don't have to include every command one by one in the list.See below

4lw.commands.whitelist=*

As you have not shared your logs that's a starting point, then restart your zookeeper and let me know!
