File transmission method, apparatus, and distributed cluster file system

A file transmission method, comprising:

• obtaining, by a master push node, file information of a to-be-transmitted file from a distributed coordination node cluster;
• determining, by the master push node, that at least one slave push node stores the to-be-transmitted file according to the file information of the to-be-transmitted file and heartbeat information of the at least one slave push node;
• wherein the heartbeat information of the at least one slave push node contains file information stored in the at least one slave push node, and the to-be-transmitted file is retrieved by the at least one slave push node from a file storage node cluster;
• generating, by the master push node, a file transmission path, wherein the file transmission path comprises at least one destination node cluster;
• sending, by the master push node, the file transmission path to the at least one slave push node, so that the at least one slave push node sends the to-be-transmitted file to the at least one destination node cluster through the file transmission path;
• and
• wherein each of the at least one destination node cluster comprises a plurality of destination nodes.

A file transmission apparatus, comprising:

• a file information obtaining module, to obtain file information of a to-be-transmitted file from a distributed coordination node cluster;
• a to-be-transmitted file determining module, to determine that at least one slave push node stores the to-be-transmitted file according to the file information of the to-be-transmitted file generated by the distributed coordination node cluster and heartbeat information of the at least one slave push node, wherein the heartbeat information of the at least one slave push node contains file information stored in the at least one slave push node, and the to-be-transmitted file is retrieved by the at least one slave push node from the file storage node cluster;
• a path generating module, to generate a file transmission path, wherein the file transmission path comprises at least one destination node cluster;
• and
• a path sending module, to send the file transmission path to the at least one slave push node, so that the at least one slave push node sends the to-be-transmitted file to the at least one destination node cluster through the file transmission path, wherein each of the at least one destination node cluster comprises a plurality of destination nodes.
