Provided are a data processing method, a cluster manager, a resource manager and a data processing system. The method includes: receiving a data redistribution request; instructing, according to the data redistribution request, a first resource manager to split original data stored in a first node and import each split sub-original-data into a corresponding second node, where the first resource manager is configured to manage data stored in the first node; and instructing the first resource manager to import incremental data which is stored in the first node during splitting and importing processes into a second node corresponding to the incremental data.
