Abstract
The present invention discloses a distributed system and a data operation method thereof. The system comprises a client, a master node, a plurality of storage nodes and a plurality of computing nodes. The client is configured to send a data operation request to the master node. The master node is configured to respond to the client's request, acquire a storage node list, and then send the storage node list to the client. The plurality of storage nodes are configured to store data requested by the client for operation. The plurality of computing nodes are configured to execute a computing task allocated by the master node based on the client's data operation request. For acquiring the storage node list, the master node employs a copy location selection policy to select a storage node corresponding to a data copy. The copy location selection policy comprises at least one of the following manners: selecting a storage node with a low storage load, selecting a computing node with a low computing load, and selecting a storage node with a poor locality.
