Akira AJISAKA commented on HADOOP-11418:
----------------------------------------
bq. It looks like a little strange.
I agree with you. Rethinking this, the below looks clear to me. What do you
think?
{code}
String extClazz = (extClazz_conf == null) ?
System.getProperty(CONF_LZO_CLASS) : extClazz_conf;
{code}
Would you please add a regression test? If you don't want to add it, I'd like
to succeed your work.

> 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
