Subject [jira] [Commented] (SPARK-3683) PySpark Hive query generates "NULL" instead of None
Date Mon, 27 Oct 2014 23:24:34 GMT


Davies Liu commented on SPARK-3683:

[~jamborta] Could you show some code to reproduce it?

[~marmbrus] I think this also happens in Scala, we did not do data conversion for StringType,
it should be `NULL` in Spark SQL/Scala also.

> When I run a Hive query in Spark SQL, I get the new Row object, where it does not convert
Hive NULL into Python None instead it keeps it string 'NULL'. 
> It's only an issue with String type, works with other types.
