Hi, I am experimenting with zookeeper server node replacement using 3.5.0 version. In my setup I have 3 zookeeper servers forming a quorum and want to replace all 3 zookeeper servers with brand new instances of servers.
If I replace all 3 nodes in quick succession (using reconfig -remove x -add y). Is there a possibility zookeeper data may not be resynced completely on the new instances of zookeeper servers due to quick succession. As I observed that some data nodes (znodes) are not present in the zookeeper database after replacing all members in the quorum. Is there any way I can avoid this and how should I ensure data has been resynced before proceeding for next server replacement. Appreciate you help. Thanks & Regards, Deepak
