Summary: Unnecessary conversion try and some missing cases for special
floats in JSON (was: Parsing JSON with some NaN and Infinity values throws
NumberFormatException)
> Unnecessary conversion try and some missing cases for special floats in JSON
> ----------------------------------------------------------------------------
>
> Key: SPARK-18772
> URL: https://issues.apache.org/jira/browse/SPARK-18772
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.2
> Reporter: Nathan Howell
> Priority: Minor
>
> JacksonParser tests for infinite and NaN values in a way that is not
> supported by the underlying float/double parser. For example, the input
> string is always lowercased to check for {{-Infinity}} but the parser only
> supports titlecased values. So a {{-infinitY}} will pass the test but fail
> with a {{NumberFormatException}} when parsing. This exception is not caught
> anywhere and the task ends up failing.
> A related issue is that the code checks for {{Inf}} but the parser only
> supports the long form of {{Infinity}}.
