Re: Building Hadoop from source code
@Mohammad Mustaqeem - Once you create the patch as given in the 'How to
contribute to Hadoop' and apply the patch. The  changes will be reflected
in the files you have modified.

1.Now you trigger the build ant or maven. I tried with ant so the ant
command I gave is  ant clean compile bin-package. Don't forget to download
ivy.jar and copy into you ant home/ lib folder. Once the build is triggered
Hadoop should get built along with the changes you made.

If , I am not mistaken , you modified some hadoop files say
BlockLocation.java, in your
Hadoopx.x\src\core\org\apache\hadoop\fs\BlockLocation.java.

The jar will be in Hadoopx.x\build\hadoop-0.20.3-dev-core.jar(In my version)

Hope this clears your doubt.

Regards
Niranjan Singh
