Before you begin Data Engineering Integration between the domain and Hadoop environments, verify that Informatica and third-party products are installed.
You must install the following products:
Informatica domain and clients
Install and configure the Informatica domain and the Developer tool. The Informatica domain must have a Model Repository Service, a Data Integration Service, and a Metadata Access Service.
Hadoop File System and MapReduce
The Hadoop installation must include a Hive data warehouse with a non-embedded database for the Hive metastore. Verify that Hadoop is installed with Hadoop File System (HDFS) and MapReduce on each node. Install Hadoop in a single node environment or in a cluster. For more information, see the Apache website:
Database client software
To access relational databases in the Hadoop environment, install database client software and drivers on each node in the cluster.
