3.1. Gather Hadoop Cluster Information

To deploy your HDP installation, you need to collect the Hostname OR IPv4 address of each the following cluster component:

  • Required Components:

    • NameNode and optional Secondary NameNode

    • ResourceManager

    • Hive Server

    • SlaveNode

    • WebCat

    • Client Host

  • Optional Components:

    • ZooKeeper

    • HBase Master

    • Flume

    • Knox Gateway

    • Microsoft SQL Server configured with a Hive and Oozie database instance, system account names and passwords

[Important]Important

The installer fails if it cannot resolve the hostname of each cluster node. To determine the hostname for a particular cluster node, open the command line interface on that system and execute hostname and then nslookup hostname to verify that the name resolves to the correct IP address.
