The Spark engine logs appear in the LDTM log. The LDTM logs the results of the Spark engine execution plan run for the mapping. You can view the LDTM log from the Developer tool or the Monitoring tool for a mapping job.
The log for the Spark engine shows the following:
Step to translate the mapping to an internal format
Steps to optimize the mapping
Steps to render the mapping to Spark code
Steps to submit the code to the Spark executor
Scala code that the Logical Data Translation Generator creates from the mapping logic
Total number of cluster nodes used to execute the mapping
When you run Sqoop mappings on the Spark engine, the Data Integration Service prints the Sqoop log events in the mapping log.
