I get an Invalid ID when I try to access pastebin, so I haven't seen the actual code. But in the snippet below method that is not getting called should be named configure, not config.
public class BuildGraph extends MapReduceBase implements Mapper<> { @Override public void configure(JobConf conf) { ... } @Override public void map() { ... } } Dave Shine Sr. Software Engineer 321.939.5093 direct | 407.314.0122 mobile CI Boost(tm) Clients Outperform Online(tm) www.ciboost.com<http://www.ciboost.com/> From: jamal sasha [mailto:jamalsha...@gmail.com] Sent: Tuesday, January 15, 2013 9:04 PM To: user@hadoop.apache.org Subject: Re: newbie question Hi, The relevant code snippet posted here http://pastebin.com/DRPXUm62 On Tue, Jan 15, 2013 at 5:31 PM, jamal sasha <jamalsha...@gmail.com<mailto:jamalsha...@gmail.com>> wrote: My bad.

JobClient.runJob(conf); } But the problem is config method in the code is not executing as though "currentId" returns 299 in main loop but it is not set at all in the mapper class. what am i doing wrong ________________________________ The information contained in this email message is considered confidential and proprietary to the sender and is intended solely for review and use by the named recipient.
