CLDB View

The CLDB view provides information about the Container Location Database (CLDB). The CLDB is a management service that tracks container locations and the root of volumes.

To display the CLDB view, open the MapR Control System and click CLDB in the navigation pane. Alternatively, you can use the following links to access the CLDB view:
  • For a secure cluster, access the CLDB view at https://<cldbmaster>:7443/cldb.jsp.
  • For a non-secure cluster, access the CLDB view at http://<cldbmaster>:7221/cldb.jsp.

The following table describes the fields on the CLDB view:
