Summary: GenerateOrdering fails for NullType (i.e. ORDER BY NULL
crashes)

Project: Spark
Issue Type: New Feature
Components: SQL

Reporter: Josh Rosen
Assignee: Josh Rosen
Priority: Blocker
Queries containing ORDER BY NULL currently result in a code generation
exception:
{code}
public SpecificOrdering
generate(org.apache.spark.sql.catalyst.expressions.Expression[] expr) {
return new SpecificOrdering(expr);
}
class SpecificOrdering extends
org.apache.spark.sql.catalyst.expressions.codegen.BaseOrdering {
private org.apache.spark.sql.catalyst.expressions.Expression[]
expressions = null;
public
SpecificOrdering(org.apache.spark.sql.catalyst.expressions.Expression[] expr) {
expressions = expr;
}
@Override
public int compare(InternalRow a, InternalRow b) {
InternalRow i = null; // Holds current row being evaluated.
i = a;
final Object primitive1 = null;
i = b;
final Object primitive3 = null;

// Nothing
} else if (true) {
return -1;
