High Availability

You can configure the Data Integration Service and the Developer tool to run streaming mappings in a highly available Hadoop cluster. You can configure high availability for the streaming mapping.
Before you configure high availability for the mapping, verify the following prerequisites:
  • The Hadoop cluster must be highly available.
  • The Informatica domain, the Data Integration Service, and the Model Repository Service should be highly available.
  • If the mapping has Kafka sources in it, the Kafka cluster should be highly available.
For information about Informatica domain high availability, see the
