Reynold Xin commented on SPARK-11753:
-------------------------------------

I don't think this is urgent, so take your time. Note that we also have some 
custom code to handle NaN in the json parser ourselves. Ideally we should 
remove those code and just let Jackson handle them.


> Understand why allowNonNumericNumbers JSON option doesn't work

> In SPARK-11745, I introduced an undocumented option allowNonNumericNumbers. 
> According to Jackson's documentation, this option should support converting 
> "NaN", "INF", "-INF" etc into floating point numbers. However, the 2 test 
> cases in JsonParsingOptionsSuite.scala were not working and as a result were 
> ignored.
> The goal of this task is to figure out why they were not working, and 
> re-enable them.
