In some examples, a distributed system may include a plurality of nodes with a file stored in a file system across the plurality of nodes. One of the nodes may receive a request for location data corresponding to a part of the file. For instance, the location data may be included in a mapping file, and the request may specify an offset of the mapping file. The mapping file may include locations of nodes storing parts of the file in the file system across the plurality of nodes, and the mapping file may have a plurality of parts corresponding to the parts of the file. In response to the request, the node may access the mapping file and send location data corresponding to the offset of the mapping file. The location data may indicate at least one of the nodes storing the part of the file.
