Abstract: The distributed data processing method includes receiving storage information of a logical volume; receiving a data reading or writing command sent by the user, and determining a first storage information according to the data reading or writing command and the storage information of the logical volume; determining a data processing node corresponding to each group of four-tuple storage information according to the tree identifier and the data block identifier in each group of four-tuple information; and sending, by the cluster client processing apparatus, a data processing command to the data processing node corresponding to each group of four-tuple information. The distributed data processing method and apparatus avoid a resource consumption problem brought by a need for global setting or Bitmap reading/writing in a distributed storage system, and improve data processing efficiency.
