Journal Node Sync - moving to new machine


We have three journal nodes. One was creating issue of sync with name node. Even after multiple rolling restart did not fix sync issue.


Later we moved, Journal node services to another node but we again got sync issue with new host’s - journal node to name node.


Another things observed here is, location /Data0/dfs/jn directory was empty on new journal node host after moving one journal node service there.


Restart of Zookeeper & Journal node did not enable creation of edit logs on new host as well. We have also tried to move everything from working/old JN's location /Data0/dfs/jn/hanameservice/* to new host as per below section.


Can you please suggest, how to enable sync of Journal node with namenode or what step actually we are missing here?
