%json magick of dataframe drops the datatype information
Hi,
I'm trying to understand why, when I use %json magic, dataType is empty? As you can see in this gist:

<https://gist.github.com/harschware/a29dc3224d3dea6bb749790244d39d72>
all structs in the schema come back with just "name" and "nullable" populated. But, as you can see in values I have two columns that are integer and the rest are string. This matches the definition of the hive table. and I can verify it by sending d.printSchema() to livy.
Should this be populated with the datatype, or am I missing something?
Thanks,
Tim
