Hello,
  We were trying to build the hadoop source code but getting a
 lot of errors(100 to be precise). We used the ant package to build the
haddop. Tried it from both the HADOOP_HOME folder and the src folder but
 the errors continue to happen. Can someone please help us out.

Thanking you

Yours faithfully
Ranjan Banerjee

we had similar problems will back. Here few tips that might help your
build:
1) always start a newly downloaded build with clean option - ant clean
2) make sure you have your build path set correctly, example:
 export JAVA_HOME=/opt/jdk1.6.0_31
export PATH=/opt/jdk1.6.0_31/bin:$PATH
export CLASSPATH=/opt/jdk1.6.0_31/jre/lib

Hello Amir Sanjar,
  Thanks for your help. The classpath was not set. We set it and now it is working fine.

Regards,
Ranjan

You'll probably get better help if you give details on what OS you're
using, which JDK, version of hadoop, an example error, etc.
