-----------------------------------
Potential fix by [~wdberkeley]: https://gerrit.cloudera.org/#/c/3142/
> NaN float and double values are not handled correctly
> -----------------------------------------------------
>
> Key: KUDU-1386
> URL: https://issues.apache.org/jira/browse/KUDU-1386
> Project: Kudu
> Issue Type: Sub-task
> Components: tserver
> Reporter: Dan Burkert
> Assignee: Will Berkeley
> Priority: Minor
>
> {{TypeInfo<FLOAT>::Compare}} and {{TypeInfo<DOUBLE>::Compare}} always return
> 0 when one of the arguments is a {{NaN}} value. This results in equality
> predicates never filtering {{NaN}} values. {{TypeInfo::Compare}} should be
> changed so that it doesn't assume that the data type is totally ordered.
