Configuration Interpretation

• tickTime=2000: Communication heartbeat time, zookeeper server and client heartbeat time, in milliseconds.
• initLimit=10: LF initial communication time limit. The maximum number of heartbeats that the Leader and Foolower can tolerate when they initially connect.
• syncLimit=5: LF synchronous communication time limit.
• dataDir: Save the data in zookeeper. By default, it is stored in the tmp directory, which is easy to be deleted periodically by Linux.
