        Read
        Advanced
         tab, and verify whether the file path in the
        File path
         field corresponds to the data source in the Linux or Windows machine.
      You can choose the Resource Format as
      Avro
       or
      Parquet
       only for flat-structured Avro and Parquet data sources.
      You can choose a folder with multiple Avro or multiple Parquet files to create a data object. After you create the data object, navigate to
      Data Object Operations
      Read
      Advanced
       tab, and verify whether the file path in the
      File path
       field points to the folder of the data sources in the Linux or Windows machine.
