Please let me know how to set the Jobconf what should be the values for this. With my setup I can run Java programs. My Observations: The program /home/ramaswamy_a/hadoop/src/examples/pipes/impl/wordcount-simple.cc is including the file /home/ramaswamy_a/hadoop/c++/Linux-i386-32/include/hadoop/Pipes.hh. Pipes.hh contains JobConf which is an abstract class. Is it needed to write to our own JobConf by inheriting the Pipes.hh:JobConf class? Please suggest me Thanks and Regards Ramaswamy .
