Jason, the easiest way to debug a MapRedupe program with eclipse is working on hadoop local. http://hadoop.apache.org/common/docs/r0.20.2/quickstart.html#Local In this mode all the components run locally on the same VM and can be easily debugged using Eclipse. Hope this will be useful.

For each DataNode, its IP address is like :192.168.0.XXX; 2. For the NameNode, it has two network cards: one is connect with the DataNodes as a local LAN with IP address 192.168.0.110, while the other one is connect to the company network(which eventually connect to the Internet); -- now I'm trying to debug a MapReduce program on a computer which is in the company network. Since the jobtracker in this scenario is 192.168.0.110:9001<http://192.168.0.110:9001>, I was wondering how could I connect to the cluster by using eclipse? -- YANG, Lin ________________________________ Subject to local law, communications with Accenture and its affiliates including telephone calls and emails (including content), may be monitored by our systems for the purposes of security and the assessment of internal compliance with Accenture policy. ______________________________________________________________________________________ www.accenture.com
