Hi, I am a new learner of hadoop and I am sorry if this question was asked a lot of times before. But I have no idea about this issue. I check out the hadoop 0.21.0 source code and build the three parts of the source code separately. All the three parts can be built successfully. But now I want to modify some source code and then deploy hadoop using the modified code. But I have no idea about how to do this. In other words, I mean how can I use the modified code? (because I want to use hadoop streaming and there is a bug in streaming for the version 0.21.0, so I need to modify some code )
Thanks & best regards, Wenjing
