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.
- Log in to the Master Node as root.
-
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
- For MASTER1, MASTER2, MASTER3, and all DATANODE# instances, record the FQDN of the node ( <nodename>.<customer>.com).
