hadoop build problems
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

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

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

Re: Hadoop: Trunk vs branch src code
Posted by Robert Evans <ev...@yahoo-inc.com>.
That depends on where you want your code to go in.
If it is a new feature then it needs to go into trunk at a minimum. Trunk and branch-2 are very similar right now so if you want it to go into the next release with MRV2 you may want to target branch-2 as well. It should be minimal effort to have it go into both trunk and branch-2. If it is something for the current stable line (MRV1) you want to target that too, but in many cases it may be a lot of effort because trunk and branch-1 have diverged significantly.

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.
