Can you please help me resolve this issue. The following is the error that I get no matter how small the input the program is fed with. I tried changing the default heap size of hadoop in the conf/hadoop-env.sh but that also did not help.
The following is the error that i get. Wrote input for Map #9 Starting Job 12/04/10 19:12:23 WARN mapred.JobClient: No job jar file set. User classes may not be found.
