1. A method for processing a failure in at least one distributed cluster, comprising:

  • receiving, by a first secondary node, a heartbeat message from a first reference node, wherein the heartbeat message comprises first indication information indicating that the first reference node is disconnected from a first Master node;

    determining, by the first secondary node according to the first indication information, that the first reference node is disconnected from the first Master node;

    detecting, by the first secondary node, whether a heartbeat message from the first Master node to the first secondary node is interrupted;

    determining, by the first secondary node, that the first secondary node is also disconnected from the first Master node when the heartbeat message from the first Master node to the first secondary node is interrupted; and

    determining, by the first secondary node, that the first Master node disconnected from both the first secondary node and the first reference node is faulty,wherein the at least one distributed cluster comprises a first distributed cluster, andwherein the first distributed cluster comprises the first Master node, a first Slave node, the first reference node, and the first secondary node that serves as a backup of the first Master node.
