Ethernet cards are required on:
  • All master, data, and edge nodes in the Hadoop cluster when the following apply:
    • Jobs are being submitted to the cluster from outside the InfiniBand network
    • Data is being loaded to or from Teradata Database and Aster Database systems that are not on the same InfiniBand network
    • A customer wants to monitor the cluster using a Viewpoint server located outside the InfiniBand network
  • All edge nodes when the following apply:
    • Jobs are only being submitted to the cluster from inside the same InfiniBand network or only through the edge node
    • Data is not being loaded to or from Teradata Database and Aster Database systems outside the InfiniBand network
External hosts access Hadoop in one of two ways:
  • For site-wide access, include the hostnames and IP addresses in your DNS configuration; DNS records need to match the hostnames returned by hostname -f, when run from a node for Hadoop.
  • If the hosts are not included in DNS, external hosts can access the Hadoop cluster by including external IP addresses, like 153.64.1.1, in DNS or in a local /etc/hosts file.
  1. Run hostname -f on each node in the Hadoop cluster to determine the Fully Qualified Domain Name (FQDN) including hostname and IP address to include in DNS or local hosts files.
  2. Add entries to your DNS configuration for the nodes, or add entries in /etc/hosts to enable individual hosts to access the Hadoop cluster.
