Hope you are doing well

I called you regarding this but could not able to reach you that time.

You can take the help of check point node to merge the fsimage and edit logs

Checkpoint Node:

A Checkpoint Node was introduced to solve the drawbacks of the NameNode. The changes are just written to edits and not merged to fsimage during the runtime. If the NameNode runs for a while edits gets huge and the next startup will take even longer because more changes have to be applied to the state to determine the last state of the metadata.

The Checkpoint Node fetches periodically fsimage and edits from the NameNode and merges them. The resulting state is called checkpoint. After this is uploads the result to the NameNode.

I hope this will resolve your query
