Effective in version 10.2.1, you can create a Metadata Access Service. The Metadata Access Service is an application service that allows the Developer tool to access Hadoop connection information to import and preview metadata. When you import an object from a Hadoop cluster, the following adapters use Metadata Access Service to extract the object metadata at design time:
PowerExchange for HBase
PowerExchange for HDFS
PowerExchange for Hive
PowerExchange for MapR-DB
For more information, see the "Metadata Access Service" chapter in the
Informatica 10.2.1 Application Service Guide.
