Assignee: Marta Kuczora
> beeline outputformat needs better documentation
> -----------------------------------------------
>
> Key: HIVE-14632
> URL: https://issues.apache.org/jira/browse/HIVE-14632
> Project: Hive
> Issue Type: Improvement
> Components: Beeline
> Affects Versions: 0.14.0
> Environment: Hive HiveServer2 wiki
> Reporter: Michael Howard
> Assignee: Marta Kuczora
>
> SUMMARY
> * need better wiki page doc for beeline outputformat option
> * should explicitly say that "double quote characters" are used to enclose
> fields which need enclosing.
> * Should describe the treatment of embedded double quote chars as "doubled"
> DETAIL
> The page at:
> https://cwiki.apache.org/confluence/display/Hive/HiveServer2+Clients#HiveServer2Clients-Separated-ValueOutputFormats
> describes separated value outputformats csv/tsv/csv2/tsv2, etc.
> I found doc to be inadequate and terminology to be confusing.
> > These conform better to standard CSV convention, which adds quotes around a
> > cell value
> What kind of quotes? The only reference to quotes in this section refers to
> single quotes for the deprecated csv/tsv format.
> The JIRA at
> https://issues.apache.org/jira/browse/HIVE-8615
> clarifies a bit:
> - Old format quoted every field. New format quotes only fields that contain a
> delimiter or the quoting char.
> - Old format quoted using single quotes, new format quotes using double
> quotes
> - Old format didn't escape quotes in a field (a bug). New format does escape
> the quotes
> However, neither this JIRA page nor the wiki page doc define what is meant by
> "escaping the quotes".
> Q: In this context, does escaping mean "backslash escaping" or "double
> embedded double quotes" or something else?
> Investigation of source code reveals that this is using SuperCSV.
> SuperCSV does not support backslash-escape of embedded quotes. See last line
> of:
> https://super-csv.github.io/super-csv/csv_specification.html
> THE END
