Liwei Lin updated SPARK-16462:
------------------------------
Description:
When casting given string datum to specified type, CSV should return {{null}}
for nullable types if {{datum == options.nullValue}}.
However, for certain data types like {{Boolean}}, {{TimestampType}},
{{DateType}}, CSV in 2.0 does not return {{null}} for some "empty" datum. This
is a regression comparing to 1.6.

However, for certain data types like {{Boolean}}, {{TimestampType}},
{{DateType}}, CSV in 2.0 does not return {{null}} for datum which equals to
{{options.nullValue}}. This is a regression comparing to 1.6.
