Delimited Text Formats and Field and Line Delimiter Characters

HCatalog supports delimited text format as one of the table storage formats. But when delimited text is used and the imported data has fields that contain those delimiters, then the data may be parsed into a different number of fields and records by Hive, thereby losing data fidelity.

For this case, one of these existing Sqoop import options can be used:

  • --hive-delims-replacement

  • --hive-drop-import-delims

If either of these options is provided on input, then any column of type STRING will be formatted with the Hive delimiter processing and then written to the HCatalog table.
