Answer 1

Hey,

To create an Ephemeral Znode, add -e flag as shown below:-

Syntax:-

create -e /path /data

Sample:-

create -e /SecondZnode “Ephemeral-data”

Output:-

[zk: localhost:2181(CONNECTED) 2] create -e /SecondZnode “Ephemeral-data”
Created /SecondZnode

Remember when a client connection is lost, the ephemeral znode will be deleted. You can try it by quitting the ZooKeeper CLI and then re-opening the CLI.
