You can add a connection to a Hive database using ThoughtSpot DataFlow.

Follow these steps:

  1. Click Connections in the top navigation bar.

  2. In the Connections interface, click Add connection in the top right corner.

  3. In the Create Connection interface, select the Connection type.

  4. After you select the Hive Connection type, the rest of the connection properties appear.

    See Connection properties for details, defaults, and examples.

    • Connection name
      Name your connection.

    • Connection type
      Choose the Hive connection type.

    • DFS name service
      Specify the logical name of the HDFS nameservice.

    • DFS name node IDs
      Specify a comma-separated list of NameNode IDs. System uses this property to determine all NameNodes in the cluster. XML property name is dfs.ha.namenodes.dfs.nameservices.

    • RPC address for namenode1
      Specify the fully-qualified RPC address for each listed NameNode. Defined as dfs.namenode.rpc-address.dfs.nameservices.name node ID 1. For DFS HA and Hadoop Extract only.

    • RPC address for namenode2
      Specify the fully-qualified RPC address for each listed NameNode. Define as dfs.namenode.rpc-address.dfs.nameservices.name node ID 2.

    • DFS host
      Specify the DFS hostname or the IP address.

    • DFS port
      Specify the associated DFS port.

    • Default DFS location
      Specify the location for the default source/target location.

    • Temp DFS location
      Specify the location for creating temp directory.

    • DFS security authentication
      Select the type of security being enabled.

    • Hadoop RPC protection
      Hadoop cluster administrators control the quality of protection using the configuration parameter hadoop.rpc.protection.

    • Hive principal
      Principal for authenticating hive services.

    • User principal
      To authenticate via a key-tab you must have supporting key-tab file which is generated by Kerberos Admin and also requires the user principal associated with Key-tab (Configured while enabling Kerberos).

    • User keytab
      To authenticate via a key-tab you must have supporting key-tab file which is generated by Kerberos Admin and also requires the user principal associated with Key-tab (Configured while enabling Kerberos).

    • KDC host
      Specify KDC Host Name where as KDC (Kerberos Key Distribution Center) is a service than runs on a domain controller server role (Configured from Kerberos configuration-/etc/krb5.conf).

    • Default realm
      A Kerberos realm is the domain over which a Kerberos authentication server has the authority to authenticate a user, host or service (Configured from Kerberos configuration-/etc/krb5.conf).

    • Queue name
      Specify the queue name followed by a coma separated form in yarn.scheduler.capacity.root.queues. For Hadoop Extract only.

    • YARN web UI port
      Yarn Providing web UI for yarn RM and by default 8088 in use. For Hadoop Extract only.

    • Zookeeper quorum host
      Specify the value of hadoop.registry.zk.quorum from yarn-site.xml. Only when not using Hiveserver2 HA.

    • Yarn timeline webapp host
      Specify the ip address of yarn timeline service web application.
