The Data Integration Service generates log events when you run a mapping in the Hadoop environment.
You can view logs for the Blaze engine, the Spark engine, or the Hive on MapReduce engine. You can view log events relating to different types of errors such as Hadoop connection failures, Hive query failures, Hive command failures, or other Hadoop job failures.
You can view the Scala code that the Logical Data Translation Generater generates from the Informatica mapping.
You can view reject files in the reject file directory specified for the Data Integration Service.
