I am getting this error-

Hi @ds_explorer, it seems because the edit log is too big and cannot be read by NameNode completely on the default/configured timeout.

2022-06-25 08:32:24,872 ERROR org.apache.hadoop.hdfs.server.namenode.NameNode: Failed to start namenode.
org.apache.hadoop.hdfs.server.namenode.EditLogInputException: Error replaying edit log at offset 554705629. Expected transaction ID was 60366342312

To fix this, can you add the below parameter and value (if you already have then kindly increase the value)

HDFS > Configuration > JournalNode Advanced Configuration Snippet (Safety Valve) for hdfs-site.xml

hadoop.http.idle_timeout.ms=180000 

And then restart the required services.
