Some processing rules for the Blaze engine differ from the processing rules for the Data Integration Service.
Mapping validation fails in the following situations:
The cache is configured to be shared, named, persistent, dynamic, or uncached. The cache must be a static cache.
If you add a data object that uses Sqoop as a Lookup transformation in a mapping, the Data Integration Service does not run the mapping through Sqoop. It runs the mapping through JDBC.
