Issue Type: Bug
Components: File Formats
Affects Versions: 0.15.0
Reporter: Gopal V
Assignee: Gopal V
Fix For: 0.15.0
ORC PPD returns IS_NULL wrong for the fuzz case of some-nulls.
The code-flow in effect should be
{code}
if (min == null) {
// all nulls
return YES;
} else {
if (hasNull == true) {
// some nulls
return YES_NO; //maybe
}
// no nulls
return NO;
}
{code}
