Configure the Data Sources

You must configure NWDB, Warehouse, and Respond to generate Reports, Charts, and Alerts. Optionally, you can also configure Archiver, Collection, and Workbench data sources.

IMPORTANT: If you change the admin password on a NetWitness service that is used as a Reporting Engine data source, you must remove and then re-add the service as a data source.

Note: To execute Reports and Charts on an Analyst UI, make sure the admin adds the data sources to each Reporting Engine instance from the admin node using the relevant procedure described in this topic.

  7. The service is displayed in the Sources tab when it is successfully added.

Note: The services with the Trust Model enabled must be added individually. You are prompted to provide a username and password for the selected service.

Configure a Warehouse Data SourceConfigure a Warehouse Data Source

You can add the warehouse data source to Reporting Engine, so that you can extract the data from the required services, store them in MapR or Horton works and generate Reports and Alerts. The procedure to configure Warehouse as a data source differs. To extract data from a Warehouse data source, you must configure it using the following procedure.

Note: Warehouse Connector is still supported, as it is reporting against a warehouse in NetWitness 11.x.

PrerequisitePrerequisite

Make sure you:

  • Add a Warehouse Data Source to Reporting Engine.
  • Set Warehouse Data Source as the Default Source.

  • HIVE server is in running state on all the Warehouse nodes. Use the following command to check the status of the HIVE server:

    status hive2 (MapR deployments)
    service hive-server2 status (Horton Works deployments)

  • Warehouse Connector is configured to write data to the warehouse deployments.

  • If Kerberos authentication is enabled for HiveServer2, make sure that the keytab file is copied to the /var/netwitness/re-server/rsa/soc/reporting-engine/conf/ directory in the Reporting Engine Host.

    Note: The rsasoc user should have read permissions for the keytab file. For more information, see Configure Data Source Permissions.

    Also, make sure that you update the keytab file location in the Kerberos Keytab File parameter in the Reporting Engine Service Config View. For more information, see Reporting Engine General Tab.

To add Warehouse data source for MapR:

  1. Go to netwitness_adminicon_25x22.png (Admin) > Services.
  2. In the Services list, select the Reporting Engine service.

  3. Click netwitness_settings.png > View > Config.

    The Service Config view is displayed with the General tab open.

  4. Click the Sources tab.

  5. In the Sources tab, click netwitness_ic-adddrop.png and select New Service.

    The New Service dialog is displayed.

    netwitness_wc_device_re_382x414.png

  6. In the Source Type drop-down menu, select WAREHOUSE.
  7. In the Warehouse Source drop-down menu, select the warehouse data source.
  8. In the Name field, enter the host name of the Warehouse data source.

  9. In the HDFS Path field, enter the HDFS root path to which the Warehouse Connector writes the data.

    For example:

    If /saw is the local mount point for HDFS that you have configured while mounting NFS on the device. And if you have installed the Warehouse Connector service to write to SAW. For more information, see "Mount the Warehouse on the Warehouse Connector" topic in the Warehouse (MapR) Configuration Guide.

    If you have created a directory named Ionsaw01 under /saw and provided the corresponding Local Mount Path as /saw/Ionsaw01, then the corresponding HDFS root path would be /Ionsaw01.​

    The /saw mount point implies to /as the root path for HDFS. The Warehouse Connector writes the data /Ionsaw01 in HDFS. If there is no data available in this path, the following error is displayed:

    “No data available. Check HDFS path”

    Make sure that /lonsaw01/rsasoc/v1/sessions/meta contains avro files of the meta data before performing test connection.

  10. Select the Advanced checkbox to use the advanced settings, and fill in the Database URL with the complete JDBC URL to connect to the HiveServer2.

    For example:

    If kerberos is enabled in HIVE then the JDBC url will be:

    jdbc:hive2://<host>:<port>/<db>;principal=<Kerberos serverprincipal>

    If SSL is enabled in HIVE then the JDBC url will be:

    jdbc:hive2://<host>:<port>/<db>;ssl=true;sslTrustStore=<trust_store_path>;trustStorePassword​=<trust_store_password>

    For more information on HIVE server clients, see https://cwiki.apache.org/confluence/display/Hive/HiveServer2+Clients.

  11. If not using the advanced settings, enter the values for the Host and Port.

    • In the Host field, enter the IP address of the host on which HiveServer2 is hosted.

      Note: You can use the virtual IP address of MapR only if HiveServer2 is running on all the nodes in the cluster.

    • In the Port field, enter the HiveServer2 port of the Warehouse data source. By default, the port number is 10000.

  12. In the Username and Password field, enter the JDBC credentials used to access HiveServer2.

    Note: You can also use LDAP mode of authentication using Active Directory. For instructions to enable LDAP authentication mode, see Enable LDAP Authentication.

  13. Enable Kerberos authentication: see Enable Kerberos Authentication.
  14. ​If you want set the added Warehouse data source as default source for the Reporting Engine, select the added Warehouse data source and click netwitness_setdefault.png.

To add Warehouse data source for Horton Works (HDP):
