Hadoop Environment Logs

The Data Integration Service generates log events when you run a mapping in the Hadoop environment.

You can view logs for the Blaze and Spark engines. You can view log events relating to different types of errors such as Hadoop connection or job failures.

When you run a mapping on the Spark engine, you can view the Scala code in logs that the Logical Data Translation Generator generates from the Informatica mapping.

You can view reject files in the reject file directory specified for the Data Integration Service.
