      Cloudera Navigator

      Connectivity Summary

      Cloudera Navigator console audits includes events collected by Cloudera Manager:

      • Service lifecycle events: activate, create, delete, deploy, download, install, start, stop, update, upgrade etc.
      • User security related events: add / delete user, login fail / success

      OvalEdge will make a request to the Cloudera navigator using Rest API.

      We are currently making the calls to get audit events for:

        1. Hive
        2. Impala
        3. HBase
        4. HDFS

      Technical Details

      • Cloudera Navigator is connected to OvalEdge application through REST API.
      • GET operation is used to get the audit events from Cloudera navigator.
      • Audits can be Searched / Filtered by date based on the requirement.

      Pre-requisites

      To implement a connection to your Cloudera Navigator from OvalEdge, you must have the following:

      • An Admin / Service account with access
      • Connection details as specified in the below section should be available.

      Connection Details

      When you set up a Cloudera Navigator connection, you must configure the connection properties. The following are the Cloudera Navigator connection properties:

      • Database Type – Cloudera Navigator
      • License Type - Standard (by default)
      • Connection Name * : Select a Connection name for the Cloudera Navigator. The name that you specify is a reference name to easily identify the connection in OvalEdge.
        Example: Navigator Source OE
      • Cloudera Navigator URL * : IP Address / URL with port
      • Username * : User account login username
        Password * : User account login password
      • Connection Id: 
        • HDFS - Connection Id of crawled HDFS connection in OvalEdge
        • HBase  - Connection Id of crawled HBase connection in OvalEdge
        • Hive - Connection Id of crawled HBase connection in OvalEdge
        • Impala - Connection Id of crawled HBase connection in OvalEdge

      Once the connectivity is established, we can now access the Navigator Audit Events from OvalEdge.

        When the following details are provided, 

          1. Connection Id's of HDFS / HBase / Hive / Impala and
          2. Connectors are crawled 
        we can navigate to respective Schema / Table from live audits integrated into OvalEdge.
