You can configure the Data Integration Service and the Developer tool to run streaming mappings in a highly available Hadoop cluster.
To run streaming mappings in a highly available Hadoop cluster, verify the following prerequisites:
  • The Hadoop cluster must be highly available.
  • The Informatica domain, the Data Integration Service, and the Model Repository Service is highly available.
  • If the mapping has Kafka sources in it, the Kafka cluster is highly available.
