[GitHub] spark issue #21273: [SPARK-17916][SQL] Fix empty string being parsed as null...

[koertkuipers <gi...@git.apache.org>]

    to summarize my findings from jira:
    this breaks any usage without quoting. for example we remove all characters from our values that need to be quoted (delimiters, newlines) so we know we will always write unquoted csv, but now we suddenly find these empty quoted strings in our output. the systems we write to cannot handle these quoted values.
