Environment Validation

Environment Validation

The Developer tool performs environment validation each time you validate a streaming mapping.
The Developer tool generates an error in the following scenarios:
  • The mapping has Native environment.
  • The mapping does not have a Spark validation environment and Hadoop execution environment.
  • The mapping has a Hadoop execution environment and has Native, Blaze, and Spark validation environment.


We’d like to hear from you!
