Preparing the Internal Hadoop Cluster Environment

Preparing the Internal Hadoop Cluster Environment

You need to perform multiple validation checks before you can before you install Enterprise Data Catalog on an internal Hadoop cluster.
Perform the following steps before you install Enterprise Data Catalog on an internal Hadoop cluster environment:
  • Configure the
    /etc/hosts
    file on each machine so that you have fully qualified domain names. Informatica recommends the following host name format in lowercase:
    <machine ipaddress> <fully qualified name> <alias>
    .
    To verify the configured host name, run the
    #hostname -f
    command.
  • Set up passwordless Secure Shell (SSH) connections between the following components:
    • From Informatica Cluster Service to Hadoop Gateway.
    • From the Hadoop Gateway to Apache Hadoop nodes.
  • Make sure that the
    /etc/hosts
    file on the machine that hosts Informatica domain includes entries for all Hadoop hosts.
