Subject [jira] [Updated] (SPARK-21678) Disabling quotes while writing a dataframe
Date Wed, 09 Aug 2017 13:27:00 GMT

     [ https://issues.apache.org/jira/browse/SPARK-21678?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Taran Saini updated SPARK-21678:
--------------------------------
    Description: 
Hi,

I have the my dataframe cloumn values which can contain commas, double quotes etc.
I am transforming the dataframes in order to ensure that all the required values are escaped.

However, on doing df.write.format("csv")
It again wraps the values in double quotes. How do I disable the same? 
And even if the double quotes are there to stay why does it do the following :
L"\, p' Y a\, C G is written as "L\"\\, p' Y a\\, C G\\, H" i.e double escapes the next already
escaped values. 
and if i myself escape like :
L\"\, p' Y a\, C G then that is written as  "L\\"\\, p' Y a\\, C G\\, H"

How do we just disable this automatic escaping of characters?
