Before the Informatica administrator can import cluster information to create a cluster configuration in the Informatica domain, the Hadoop administrator must perform some preliminary tasks.
Perform this task in the following situations:
You are integrating for the first time.
You upgraded from any previous version.
If you are upgrading from a previous version, verify the properties and suggested values, as Data Engineering Integration might require additional properties or different values for existing properties.
Complete the following tasks to prepare the cluster before the Informatica administrator creates the cluster configuration:
Verify property values in *-site.xml files that Data Engineering Integration needs to run mappings in the Hadoop environment.
Provide information to the Informatica administrator that is required to import cluster information into the domain. Depending on the method of import, perform one of the following tasks:
To import directly from the cluster, give the Informatica administrator cluster authentication information to connect to the cluster.
To import from an archive file, export cluster information and provide an archive file to the Data Engineering Integration administrator.
