Data cleaning system of distributed cluster

The invention relates to the technical field of data cleaning, in particular to a distributed cluster data cleaning system which comprises a first target node ID, a preset data block OID priority list, a processor and a memory storing a computer program. The method comprises the following steps: when a repair instruction sent by a first target node is received, acquiring a first data block OID set from the first target node, acquiring a target backup data block OID received by the first target node, acquiring a target priority corresponding to the target backup data block OID according to a preset data block OID priority list, and repairing the target backup data block OID according to the target priority. And then obtaining a second data block OID set from the first data block OID set, and clearing the second data block set corresponding to the second data block OID set from the first data block set corresponding to the first data block OID set, so that the first target node completes data clearing in the re
