      1. Start bulk load of a large CSV file with pentaho bulk load adapter. File contains 121 million rows (9 GB in size).
      2. Pentaho CSV input module writes data on chunks and passes them to the Bulk Loader.
      3. After last chunk has been read the error is displayed on the server where pentaho job was run:
