> From following code, seems "io.compression.codec.lzo.class" does not work for other codec besides default. Hadoop will always treat it as defaultClazz. I think it is a bug. Please let me know if this is a work as design thing. Thanks

> 82 public synchronized boolean isSupported() {
> 83 if (!checked) {

> 85 String extClazz =
> 86 (conf.get(CONF_LZO_CLASS) == null ? System
> 87 .getProperty(CONF_LZO_CLASS) : null);
> 88 String clazz = (extClazz != null) ? extClazz : defaultClazz;
