Abstract: A system and method of managing a cluster of distributed machines is described. A cluster manager receives status updates regarding tasks running on each machine in the cluster from a task tracker running on the machine. The cluster manager receives resource requests from a job tracker created by a client wishing to run a job in the cluster. The cluster manager is responsible for implementing push-based fair scheduling of resources to the job trackers. The job tracker is responsible for running tasks for one job in the resource identified by the cluster manager. In one embodiment, the job tracker can run in the client for small jobs and in the cluster for larger jobs. The cluster manager can also be restarted, for example, for software updates without restraining the cluster.

Abstract: A system and methods for parallelized backup and restore process and system are disclosed. In one embodiment, a method includes providing a massively parallelized analytic database, serializing a schedule of a transaction history of the massively parallelized analytic database, and creating a transactionally consistent copy of the massively parallelized analytic database. The method may include restoring one or more of an original system and a configurationally equivalent system to a transaction consistent state as of a time the transactionally consistent copy was created. The transactionally consistent copy may be stored on a separate system than the original system. Accessibility to the transactionally consistent copy may be retained on the separate system even when the original system is inaccessible by the storing of the transactionally consistent copy on the separate system.
