Where Is DataJoinMapperBase?
Hi, all,
I am starting to learn advanced Map/Reduce. However, I cannot find the
class DataJoinMapperBase in my downloaded Hadoop 1.0.0 and 0.20.2. So I
searched on the Web and get the following link.
http://www.java2s.com/Code/Jar/h/Downloadhadoop0201datajoinjar.htm
>From the link I got the package, hadoop-0.20.1-datajoin.jar. My question is
why the package is not included in Hadoop 1.0.0 and 0.20.2? Is the correct
way to get it?
Thanks so much!
Best regards,
Bing

Bing,
You should find the data_join contrib module under
./src/contrib/data_join, and you should be able to build from that if
its jar does not also pre-exist under ./contrib/data_join.

Hi,
Please look inside $HADOOP_HOME/contrib/datajoin folder of 0.20.2 version.
You will find the jar.
