I'm going to make a mistake when I execute this order. The requested URL/mnt/homework/apache-druid-0.15.0-incubating/var/sv/zk.log was not found on this server. The main reason is that the official website requires zookeeper to be placed in the root directory of druid as a zk folder.

Since I'm here zookeeper's installation is in a sibling directory with druid and other components. So a soft link is created in the druid installation directory, pointing to zk

cd /home/homework/druidln -s /home/homework/zookeeper zk

In this case, druid can be started.
