Modifying source code of hadoop
Hi,
I am new to hadoop. I want to make a few changes to the hadoop source code
for my college project. How can I do this? How to compile and test the
modified code? What tools are needed to perform this? Your reply will be of
great help to me.
Thanks in advance.

Hi Samaneh,
Have you checked your repository location vs. what is in the POM?
http://maven.apache.org/maven-1.x/reference/properties.html
Your local repo is probably in ~/.m2
Hope that helps.
Thanks,

I put cygwin's bin on windows PATH ,but i got the same error .
Anyway i decided to move on Ubuntu .
So I have got the hadoop source on Ubuntu and tried to build that with
"mvn clean package" ,but I got another error which complained about pom
validation :
Failed to validate pom for project hadoop-project !
any comment on that ?!

Unsure on what could cause that but I'd first check if Cygwin's bin/
items are on my Windows PATH.
FWIW, if you are stepping into development, and your development isn't
windows-specific, best to use any modern Linux distro as your
environment instead. Ubuntu works great for starters. I prefer using
ArchLinux myself.

Hello,
I am new to hadoop as well. I just followed the instruction,got the source
code and tried to build it by maven .
during the mvn install, build failed and got an error which says :
[ERROR] Failed to execute Goal org.codebus.mojo: Exec-Maven-plugin: 1.2:
Exec <generate-version> on project hadoop-yarn-common: Command execution
failed. Cannot run program 'scripts \ saveVersion.sh'
Any idea how to fix it ?
By the way the environment is windows+cygwin
Thanks
Samaneh
