Answer 1

The environmental variable that needs to be set to properly start Zookeeper is ZOOKEEPER_HOME.

Step-by-step explanation:

The environmental variable that needs to be set to properly start Zookeeper is ZOOKEEPER_HOME. This variable should be set to the directory where Zookeeper is installed.
