>                 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
