| Zusammenfassung: | The invention provides a big data cluster reset and reinstallation method and system. The state of a target file is monitored through a file tracker, the file state is stored through a state machine,when cluster installation and deployment operation is abnormal, the big data management platform conducts system recovery, if recovery fails, the last state is selected from the state machine througha restorer to conduct resetting, and cluster or component reinstallation is conducted after a problem is repaired. When irreversible abnormity occurs in the cluster deployment or component installation process, the previous normal state can be selected to be reset, and the situation that the whole cluster is unavailable and all servers need to be reinstalled with time consumed due to the fact thatnormal configuration of the system cannot be restored after installation of individual components or servers fails is avoided. The big data cluster installation error risk can be reduced, and the recovery time of an abnormal s |
