Abstract

The invention provides a failover method and a failover device of an HBase system. The method is applied to a first working node in an HBase system. The method comprises the following steps of obtaining a pre-writing log system WAL file sent by a management node in an HBase system, wherein the WAL file comprises: a WAL file; when a second working node in the HBase system breaks down, the WAL filesof a plurality of table fragments are arranged in the second working node; splitting a WAL file in a self node memory; obtaining a WAL file of each table fragment; according to the WAL file of each table fragment in the own node memory, obtaining the WAL file; and determining update data of each table fragment in the memory of the second working node when a fault occurs, and writing the update data of each table fragment into the own node hard disk, thereby realizing transfer and persistent storage of the update data of the table fragments in the memory of the second working node, and avoiding loss of the data in the memory when the second working node has the fault.

Description

technical field [0001] The present disclosure relates to the technical field of computer communication, in particular to a failover method and device for an HBase system. Background technique [0002] HBase is an open source distributed database. The services provided are deployed on multiple nodes, and multiple nodes form a distributed cluster, which is also called the HBase system. Based on the different types of services provided, the HBase system includes: management nodes and work nodes. The management nodes are used to manage the table fragmentation information of the work nodes, and the work nodes are used to receive read and write requests sent by the The write request modifies the table data of the table fragment. [0003] After the working node receives the read and write request sent by the requesting end, it modifies the table data of the table fragment in the memory according to the read and write request to obtain the updated data. When the amount of data in t...
