Connecting to HPE Ezmeral Data Fabric

Describes how to connect HPE Ezmeral Unified Analytics Software to an external HPE Ezmeral Data Fabric cluster.

To connect HPE Ezmeral Unified Analytics Software to an HPE Ezmeral Data Fabric cluster, you must provide the following information for the HPE Ezmeral Data Fabric cluster:
CLDB nodes (hostnames or IP addresses)
To get a list of the CLDB hosts, run the following command on the HPE Ezmeral Data Fabric cluster:
maprcli node listcldbs -cluster <cluster name> -json

mapruserticket
When you connect HPE Ezmeral Unified Analytics Software to an external HPE Ezmeral Data Fabric cluster, you must provide the mapruserticket to create a connection that enables users to access HPE Ezmeral Data Fabric from HPE Ezmeral Unified Analytics Software.

To get the mapruserticket, run the following command on the HPE Ezmeral Data Fabric cluster:

sudo cat /opt/mapr/conf/mapruserticket 
Volume path
This is the path to the volume in HPE Ezmeral Data Fabric that you want to connect to from HPE Ezmeral Unified Analytics Software. For information about volumes, see Managing Data with Volumes.

Complete the following steps to connect HPE Ezmeral Unified Analytics Software to an external HPE Ezmeral Data Fabric cluster:

  1. Sign in to HPE Ezmeral Unified Analytics Software.
  2. In the left navigation bar, select Administration > Data Fabrics.
  3. On the Data Fabrics page, click Add Data Fabric.
  4. In the drawer that opens, enter the following information:
    • Name - Enter the HPE Ezmeral Data Fabric name.
      IMPORTANT
      Each HPE Ezmeral Data Fabric connection that you create must have a unique name.
    • CLDB Hosts - List one or more CLDB hostnames or IP addresses with the port number. If entering more than one CLDB host, use a comma to separate each host name or IP address, for example:
      cldb.node.01:7222,cldb.node.02:7222,cldb.node.03:7222
    • Service Ticket - Paste the HPE Ezmeral Data Fabric service ticket into the field. The service ticket must include the HPE Ezmeral Data Fabric cluster name at the top. If the service ticket does not include the cluster name, the HPE Ezmeral Unified Analytics Software system cannot connect to the HPE Ezmeral Data Fabric cluster.
    • Volume Path - Enter the path to the mounted volume in the HPE Ezmeral Data Fabric cluster.
  5. Click Add. The HPE Ezmeral Data Fabric cluster is listed on the Data Fabric page. Status indicates the connection status.
    TIP
    • When you connect HPE Ezmeral Unified Analytics Software to an external HPE Ezmeral Data Fabric cluster, it can take one to two minutes for the synchronization with the cluster to complete. Once synchronized, the Data Fabric connection Status column displays Ready (green light) and the Data Fabric name changes to a clickable hyperlink.
    • You can browse the connected HPE Ezmeral Data Fabric volume from the HPE Ezmeral Unified Analytics Software UI. In the left navigation bar, go to Data Engineering > Data Sources. On the Data Sources page, click the Data Volumes tab.
