  • Publication number: 20160188628
    Abstract: In some examples, a distributed system may include a plurality of nodes with a file stored in a file system across the plurality of nodes. One of the nodes may receive a request for location data corresponding to a part of the file. For instance, the location data may be included in a mapping file, and the request may specify an offset of the mapping file. The mapping file may include locations of nodes storing parts of the file in the file system across the plurality of nodes, and the mapping file may have a plurality of parts corresponding to the parts of the file. In response to the request, the node may access the mapping file and send location data corresponding to the offset of the mapping file. The location data may indicate at least one of the nodes storing the part of the file.

  • Patent number: 9110719
    Abstract: A distributed system includes a plurality of nodes connected over a network. Each node has a unique node identifier which identifies the node in the distributed system. Tasks are launched from any node in the distributed system and include one or more node identifiers. If a node receives a task including its node identifier, the node executes the task. Each node may store each task in a log. If a node fails, after recovering from the failure, the node queries the distributed system for tasks which were not received and tasks which were not completed due to the failure.

  • Patent number: 9069784
    Abstract: In some examples, a node in a distributed system may receive one or more IP addresses for use with one or more virtual machines. For example, at least one of the received IP addresses may be encoded into a respective MAC address. Further, a hypervisor implemented on the node may configure a virtual machine on the node. For instance, configuring the virtual machine may include passing the encoded MAC address to the virtual machine through the hypervisor. The virtual machine may be configured to decode the IP address from the encoded MAC address, and the IP address is assigned to the virtual machine.
