> WritableHiveDecimalObjectInspector appears to be missing null checks in
> getPrimitiveWritableObject(Object) and getPrimitiveJavaObject(Object). The
> same checks do exist in WritableHiveVarcharObjectInspector.
> Attempting to read from a table in HCatalog containing null values for
> decimal columns results in the following exception (Pig used here):
> {noformat}
> Error: org.apache.pig.backend.executionengine.ExecException: ERROR 6018:
