When configuring Presto, you need the Fully Qualified Domain Name (FQDN) of each Teradata Appliance for Hadoop 6 node used for Presto (the Presto coordinator and worker nodes). The Hadoop 6 nodes must be connected to the byn1 network (have a byn1 IP address).
Replace the FQDNs in the examples with the FQDNs for your Hadoop nodes.
  1. Log in to the Master Node as root.
  2. Enter the following to display the Hadoop node names. hcli config show | grep 'NODE\|MASTER'

    Something similar to the following displays:

    DATANODE1=xyz721d1.customer.com 
    DATANODE2=xyz721d2.customer.com 
    DATANODE3=xyz721d3.customer.com 
    DATANODE4=xyz721d4.customer.com 
    DATANODE5=xyz721d5.customer.com 
    EDGENODE1=xyz721e1.customer.com 
    MASTER1=xyz721m1.customer.com 
    MASTER2=xyz721m2.customer.com 
    MASTER3=xyz721m3.customer.com
  3. For MASTER1, MASTER2, MASTER3, and all DATANODE# instances, record the FQDN of the node ( <nodename>.<customer>.com).
