The Informatica Cluster Service is an ISP service that manages the internal Hadoop cluster in Enterprise Data Catalog.
After Informatica Cluster Service is created, it performs the following actions:
Launches the Apache Ambari server and associated agents.
Creates Hadoop services and monitoring systems on Apache Ambari including HDFS, Apache Zookeeper, Yarn, and related monitoring services.
Starts the Hadoop services.
When you shut down Enterprise Data Catalog, the Informatica Cluster Service stops all the Hadoop services and stops the Apache Ambari server and its agents.
