A service, running on one or more MapR nodes, that maintains the locations of services, containers, and other cluster information.
NOTE

The Container Location Database (CLDB) service tracks the following information about every container in the filesystem:

  • The node where the container is located
  • Size of the container
  • The volume to which the container belongs
  • The policies, quotas, and usage for that volume
