Import the Hadoop cluster information into the domain. When you import cluster information, you import values from *-site.xml files to create a domain object called a cluster configuration.
Choose one of the following options to import cluster properties:
Import from cluster
When you import directly from the cluster, you enter cluster connection information. The Service Manager uses the information to connect to the cluster and get cluster configuration properties.
You can import directly from Azure HDInsight, Cloudera CDH, and Hortonworks HDP clusters.
Import from file
When you import from a file, you browse to an archive file that the Hadoop administrator created. Use this option if the Hadoop administrator requires you to do so.
If you import from a MapR or Amazon EMR cluster, you must import from a file.
