Answer / Uma
Hadoop Archives (ARC) are an extension to the standard Hadoop file system that allow bundling of multiple files and directories into a single archived unit. This can be useful for managing large numbers of related files. To create an archive, use the command `hadoop archives -create arc_file path/to/files`. To extract an archive, use `hadoop archives -extract arc_file path/to/destination`.
