I recently added the following to my core-site.xml
<property>
<name>io.compression.codecs</name>
<value>
org.apache.hadoop.io.compress.DefaultCodec,
org.apache.hadoop.io.compress.GzipCodec,
org.apache.hadoop.io.compress.BZip2Codec
</value>
</property>
However when I try and test a simple MR job I am seeing the following
errors in my log.
java.lang.IllegalArgumentException: Compression codec
org.apache.hadoop.io.compress.DefaultCodec not found.

Aren't these codecs installed by default? If not, how would I enable them?
Thanks
