Subject [jira] [Commented] (HIVE-14679) csv2/tsv2 output format disables quoting by default and it's difficult to enable
Date Thu, 13 Oct 2016 14:16:20 GMT

    [ https://issues.apache.org/jira/browse/HIVE-14679?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15572042#comment-15572042

Naveen Gangam commented on HIVE-14679:
--------------------------------------

Its my understanding that quoting is NOT optional for csv2/tsv2 formats. These formats were
introduced specifically to rid the quotes around the column values. Since we could not just
change the original csv/tsv formats to not wrap values in quotes for backward compatibility
reasons, we had to introduce new output formats.

Its been a while but I believe HIVE-9788 makes it optional for the original sv formats and
not affect the csv2/tsv2 formats. [~Ferd] please correct me if I am wrong.

> Over in HIVE-9788 we made quoting optional for csv2/tsv2.
> However I see the following issues:
> * JIRA doc doesn't mention it's disabled by default, this should be there an in the output
of beeline help.
> * The JIRA says the property is {{--disableQuotingForSV}} but it's actually a system
property. We should not use a system property as it's non-standard so extremely hard for users
to set. For example I must do: {{env HADOOP_CLIENT_OPTS="-Ddisable.quoting.for.sv=false" beeline
...}}
> * The arg {{--disableQuotingForSV}} should be documented in beeline help.
