Hi Joey,
Thanks. I forgot to say that; yes, the lzocodec class is listed in
core-site.xml under the io.compression.codecs property:
<property>
<name>io.compression.codecs</name>
<value>org.apache.hadoop.io.compress.GzipCodec,org.apache.hadoop.io.compress.DefaultCodec,com.hadoop.compression.lzo.LzoCodec,com.hadoop.compression.lzo.LzopCodec,org.apache.hadoop.io.compress.BZip2Codec</value>
</property>
I also added the mapred.child.env property to mapred site:
<property>
<name>mapred.child.env</name>
<value>JAVA_LIBRARY_PATH=/usr/lib/hadoop-0.20/lib</value>
</property>
per these instructions:

After making each of these changes I have restarted the cluster --
just to be sure that the new changes were being picked up.
