Use the Catalog Output step to encode CSV text file types or Parquet data formats using the schema defined in PDI to create a new resource or to replace or update an existing resource in Pentaho Data Catalog. Metadata can be added. The data is saved in the selected Hadoop or S3 ecosystem and registered as a resource in Data Catalog.
You must have role permissions in Data Catalog to write the data resources. If a new data resource is created, it must be profiled by Data Catalog to be recognized and available for use.
For more information about accessing Pentaho Data Catalog in PDI, see PDI and Data Catalog.
Note: This step is supported on the PDI engine but not on the Spark engine. Only CSV text files and Parquet data formats are currently supported.
