How to format the HDFS? How frequently it will be done?
Answer Posted / Ruchi
To format HDFS (Hadoop Distributed File System), run the `hadoop namenode -format` command. Format is usually only performed during initial setup or when a complete file system reinitialization is needed, such as after hardware changes or configuration modifications. Formatting should be minimized due to its destructive nature, as it deletes all existing data.
