Using an Open Name Parser Spark Job

  1. Create an instance of UniversalNameFactory, using its static method getInstance().
  2. Provide the input and output details for the Open Name Parser job by creating an instance of OpenNameParserDetail specifying the ProcessType. The instance must use the type SparkProcessType.
    1. Configure the open name parser rules by creating an instance of OpenNameParserConfiguration.
    2. Set the details of the Reference Data path and location type by creating an instance of ReferenceDataPath. See Enum ReferenceDataPathLocation.
    3. Create an instance of OpenNameParserDetail, by passing an instance of type JobConfig, and the OpenNameParserConfiguration and ReferenceDataPath instances created earlier as the arguments to its constructor.
      The JobConfig parameter must be an instance of type SparkJobConfig.
    4. Set the details of the input file using the inputPath field of the OpenNameParserDetail instance.
      • For a text input file, create an instance of FilePath with the relevant details of the input file by invoking the appropriate constructor.
      • For an ORC input file, create an instance of OrcFilePath with the path of the ORC input file as the argument.
      • For a Parquet input file, create an instance of ParquetFilePath with the path of the Parquet input file as the argument.
    5. Set the details of the output file using the outputPath field of the OpenNameParserDetail instance.
      • For a text output file, create an instance of FilePath with the relevant details of the output file by invoking the appropriate constructor.
      • For an ORC output file, create an instance of OrcFilePath with the path of the ORC output file as the argument.
      • For a Parquet output file, create an instance of ParquetFilePath with the path of the Parquet output file as the argument.
    6. Set the name of the job using the jobName field of the OpenNameParserDetail instance.
  3. To create and run the Spark job, use the previously created instance of UniversalNameFactory to invoke its method runSparkJob(). In this, pass the above instance of OpenNameParserDetail as an argument.
    The runSparkJob() method runs the job and returns a Map of the reporting counters of the job.
  4. Display the counters to view the reporting statistics for the job.
