Create and Use Hadoop Parameters

Create parameters to rerun a mapping with different values in the Hadoop environment. You can use parameters for sources or targets and at the mapping-level.
The following high-level steps describe how to create and use parameters in the Hadoop environment.
  • Create parameters for big data sources or targets.
  • Create mapping-level parameters.
  • Create parameter sets.
  • Create an application.
  • Optionally, generate a parameter file.
  • Run the mapping with a parameter set or optionally, run the mapping with a parameter file.
