Hello, I am working in the area of hadoop, especially i want to improve hadoop security. So i need procedure for modifying hadoop source code. I have visited this <https://wiki.apache.org/hadoop/HowToContribute>and able to compile hadoop from the source code, but i need to modify the part of the code. Is it compulsory to compile the whole hadoop, can i compile/debug a part of it. Any steps for that. Thank you.
