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 the Data Integration Service needs to run mappings in the Hadoop environment.
Prepare the archive file to import into the domain.
You cannot import cluster information directly from the Amazon EMR cluster into the Informatica domain.
