1. A map-reduce compatible distributed file system, comprising:

  • a container location database (CLDB) configured to maintain information about where each of a plurality of containers is located;

    a plurality of cluster nodes, each cluster node containing one or more storage pools, each storage pool containing zero or more containers; and

    a plurality of inodes for structuring data within said containers;

    wherein said containers are replicated to other cluster nodes with one container designated as master for each replication chain;

    wherein data in the CLDB is itself stored as inodes in well known containers;

    wherein said CLDB nodes are configured to maintain a database that contains at least the following information about all of said containers;

    nodes that have replicas of a container;

    an ordering of a replication chain for each container;
