Importing a Hadoop Cluster Configuration from a File

You can import properties from an archive file to create a cluster configuration.

Before you import from the cluster, you must get the archive file from the Hadoop administrator.

From the

Connections

tab, click the

ClusterConfigurations

node in the Domain Navigator.

From the Actions menu, select

New

Cluster Configuration

The

Cluster Configuration

wizard opens.

Configure the following properties:

Property	Description
Cluster configuration name	Name of the cluster configuration.
Description	Optional description of the cluster configuration.
Distribution type	The cluster Hadoop distribution type.
Distribution version	Version of the Hadoop distribution. Each distribution type has a default version. This is the latest version of the Hadoop distribution that Data Engineering Integration supports. When the cluster version differs from the default version, the cluster configuration wizard populates the cluster configuration Hadoop distribution property with the most recent supported version relative to the cluster version. For example, suppose Informatica supports versions 5.10 and 5.13, and the cluster version is 5.12. In this case, the wizard populates the version with 5.10. You can edit the property to choose any supported version. Restart the Data Integration Service for the changes to take effect.
Method to import the cluster configuration	Choose Import from file to import properties from an archive file.
Create connections	Choose to create Hadoop, HDFS, Hive, and HBase connections. If you choose to create connections, the Cluster Configuration wizard associates the cluster configuration with each connection that it creates. The Hadoop connection contains default values for properties such as cluster environment variables, cluster path variables, and advanced properties. Based on the cluster environment and the functionality that you use, you can add to the default values or change the default values of these properties. For a list of Hadoop connection properties to configure, see Configuring Hadoop Connection Properties. If you do not choose to create connections, you must manually create them and associate the cluster configuration with them. When the wizard creates the Hive connection, it populates the Metadata Connection String and the Data Access Connection String properties with the value from the hive.metastore.uris property. If the Hive metastore and HiveServer2 are running on different nodes, you must update the Metadata Connection String to point to the HiveServer2 host.
