> See HIVE-338.
> Hive should always use the getClassByName method from hadoop Configuration,
> so that we choose the correct ClassLoader. Examples include all plug-in
> interfaces, including UDF/GenericUDF/UDAF, SerDe, and FileFormats. Basically
> the following code snippet shows the idea:
> {code}
> package org.apache.hadoop.conf;
> public class Configuration implements Iterable<Map.Entry<String,String>> {
> ...
> /**
> * Load a class by name.
> *
> * @param name the class name.
> * @return the class object.
> * @throws ClassNotFoundException if the class is not found.
> */
> public Class<?> getClassByName(String name) throws ClassNotFoundException {
> return Class.forName(name, true, classLoader);
> }
> {code}
