Answer Posted / Bhagat Singh
Hadoop's NameNode enters Safe Mode when there are significant changes to the file system such as adding or removing directories, or after a crash. During Safe Mode, no new files can be created or deleted, and only a limited number of existing files can be modified. This is done to ensure data integrity by preventing any further modifications until the NameNode has checked all the blocks of the affected files and updated its metadata.
