Zee Chen commented on SPARK-11753:
----------------------------------
Took a quick look with jackson-core 2.4.4, the following work for both the off
and on tests: NaN, Infinity, +Infinity, -Infinity. However +INF and -INF don't
work for me for some reason.
> Understand why allowNonNumericNumbers JSON option doesn't work

> Key: SPARK-11753
> URL: https://issues.apache.org/jira/browse/SPARK-11753
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.6.0
> Reporter: Reynold Xin
>
> 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.
