More Information
Summary:The invention discloses an HDFS storage system, comprising: a plurality of metadata management nodes, a distributed system high-availability component connected with each metadata management node, a metadata storage pool. The metadata management nodes are used for receiving and processing a storage request of data to be stored. The distributed system high-availability component is used for transferring a storage request sent to the current metadata management node to another metadata management node when the current metadata management node corresponding to the current distributed system high-availability component is down. The metadata storage pool is used for storing the data to be stored, and the plurality of metadata management nodes establish communication links with the metadata storage pool. The HDFS storage system provided by the invention guarantees the data consistency in the service switching process and will not lose the data to be stored in the switching process. The invention also provides a dat
