What is the command to start a ZooKeeper server with the default configuration file?

• A. $bin/zookeeper-server-start.sh config/zookeeper.properties
• B. zookeeper-server-start config/zookeeper.properties
• C. $bin/zookeeper-start.sh config/zookeeper.properties
• D. startup zookeeper with default config

Answer: (A)

To start ZooKeeper with the default settings you use the startup script in the bin directory and point it to the default config file. The standard form is to run zookeeper-server-start.sh and pass config/zookeeper.properties as the argument, for example: $KAFKA_HOME/bin/zookeeper-server-start.sh config/zookeeper.properties. The script name must be zookeeper-server-start.sh and you need the config file path to load the default properties. Using a different script name, or omitting the bin path, or just stating a non-command phrase won’t actually start ZooKeeper.
