Description

Please check the below mentioned scenario:-

1. Configure 3 zookeeper servers in quorum
2. Start zk1 (F) and zk2(L) from a java client create a node(client connect to zk2)
3. Stop the zk2 (L)
4. Start the zk3, Now FLE is successful but zookeeper-3 is not having the node created

In step 4 Zookeeper-3 is getting a diff from the leader

but in the diff all the required data is not obtained ...!

Here I think zookeeper-3 should get snapshot from leader and not Diff
