Compression codec com.hadoop.compression.lzo.LzoCodec not found

I am runing example of wordcout but encount an exception:
I googled and know lzo compression's license is incompatible with apache's
so it's not built in.
the question is I am using default configuration of hadoop 1.2.1, why
it need lzo?
anothe question is, what's Cleaning up the staging area mean?

Re: Compression codec com.hadoop.compression.lzo.LzoCodec not found

For the codecs, you can choose
among org.apache.hadoop.io.compress.*Codec. LzoCodec has been moved out of
Hadoop (see HADOOP-4874).
