Zookeeper.service failed

Hello community,
I am trying to deploy dremio using aws marketplace (cloud formation).
Using UI Dremio I got the error message “The preview engine is not online.” The problem is the zookeeper, but I don’t know how to fix it.

Status Zookeeper | Node Executor

[root@ip-10-100-0-19 conf]# systemctl status zookeeper

What do I need to change to fix this?

@MarcosDavi The error says preview engine is not online, what happens if you click the copy icon next to the dataset and then click on 'new Query" and type "select * from ", and hit run (not preview?

Can you also do ps -ef | grep dremio on your coordinator and see if there are 2 Dremio processes running?
