Configuring the Complex File Reader for COBOL

Add a Data Processor transformation that transforms COBOL input to a mapping with a complex file reader. Configure the complex file reader to optimize how the mapping processes COBOL input in a Hive environment.
  1. In the Mapping editor, create a complex file reader object.
  2. To configure the complex file writer, perform the following steps:
    1. On the
      Advanced
      tab of the
      Properties
      view, select the
      File Format
      property, then choose
      Input Format
      .
    2. Select the
      Input Format
      property, then type
      com.informatica.hadoop.reader.RegexInputFormat
      .
    3. To optimize performance, use the
      Input Format Parameters
      property to define the regular expression in the form
      Regex="<regular expression>"
      .
  3. Create a Data Processor transformation for COBOL input using the wizard.
  4. Select the Cobol_CFR_Reader as the startup component for the Data Processor transformation.
  5. Add the Data Processor transformation to the mapping. The transformation input port should remain set to binary input, the default setting for COBOL input.
  6. Link the complex file reader output port to the Data Processor transformation input port. The complex file reader output port should remain set to binary output.
