hello, i see that the (admittedly somewhat crazy sounding) option
"treatEmptyValuesAsNulls" is missing. this used to be in spark-csv. can someone
point me to where it is or what the alternative is?
we use this setting together with the setting for "nullValue" so that empty
values come in a nulls, and nulls get written back out as empty values. this is
very typical behavior that is the default for many other frameworks such as
scalding when reading csv files.
so for example a line in a file like this:
{noformat}
a,,5
{noformat}
should become Row("a", null, 5) (this is where the "treatEmptyValuesAsNulls"
kicks in)
and going in the other direction Row("a", null, 5) should be written out again
as:
{noformat}
a,,5
{noformat}
(this is where "nullValue" kicks in)
