Patent number: 11853263Abstract: A cluster of nodes implements a single distributed file system comprises at least first and second data centers and a coordination engine process. The first data center may comprise first DataNodes configured to store data blocks of client files, and first NameNodes configured to update a state of a namespace of the cluster. The second data center, geographically remote from and coupled to the first data center by a wide area network, may comprise second DataNodes configured to store data blocks of client files, and second NameNodes configured to update the state of the namespace. The first and second NameNodes are configured to update the state of the namespace responsive to data blocks being written to the DataNodes. The coordination engine process spans the first and second NameNodes and coordinates updates to the namespace stored such that the state thereof is maintained consistent across the first and second data centers.Type: GrantFiled: August 27, 2020Date of Patent: December 26, 2023Assignee: CIRATA, INC.Inventors: Konstantin V Shvachko, Yeturu Aahlad, Jagane Sundar, Plamen Jeliazkov Jeliazkov

Patent number: 9846704Abstract: A cluster of nodes in a distributed file system may include; at least two namenodes, each coupled to a plurality of data nodes and each configured to store a state of a namespace of the cluster and each being configured to respond to a request from a client while other(s) of the namenodes are responding to other requests from other clients; and a coordination engine coupled to each of the namenodes. The coordination engine may be configured to receive proposals from the namenodes to change the state of the namespace by replicating, deleting and/or adding data blocks stored in the data nodes and to generate, in response, an ordered set of agreements that specifies an order in which the namenodes are to change the state of the namespace. The namenodes are configured to delay making changes thereto until after the ordered set of agreements is received from the coordination engine.Type: GrantFiled: July 31, 2015Date of Patent: December 19, 2017Assignee: WANdisco, Inc.Inventors: Konstantin V Shvachko, Jagane Sundar, Michael Parkin, Yeturu Aahlad
