How to Build Hadoop code in eclipse
Hi Everybody,
Is there any easy and elaborate page where its explained
how to build hadoop code. I followed http://*wiki*.apache.org/*hadoop*/*
Eclipse*Environment instruction and even video but i getting error :
BUILD FAILED : java.net.UnknownHostException : repo2.maven.org
But when accessed through browser this site is working .
I browse through proxy and I have set up user name ans password correctly.
Can any one suggest the possible soultion ?
Thanks in advance.
Regards,
Ashish

Thanks for that link. Eclipse fails miserably if left to compile on
its own, but from the instructions (your link) i added the View ->
Ant, added the root level build.xml and ran compile, which appears to
be what you are doing.
It failed a couple times connecting to sites, but repeatedly running
it eventually completed.
I was manually resolving the 4000+ compile errors by adding
appropriate jars from my eclipse plugins dir (I added 20+ jars and
still had 264 errors left).
Curious thing is TestThriftfs doesn't compile because it doesn't have
them imports:
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hdfs.DistributedFileSystem;
import org.apache.hadoop.hdfs.MiniDFSCluster;
there is no way it would ever compile no matter it be ant or eclipse.
it is probably excluded from the ant build i gather.
I finally d/led the binary version of 0.20 and that is working.
but in the eclipse build i do not find hadoop.sh ....

Running the `ant eclipse-files` target will give you nearly usable
.project and .classpath files. Import the Hadoop project into Eclipse
using these.
Or you could always checkout a stable branch/tag via SVN and go ahead
with the original wiki instructions :)

Hi All,
I wanted to ask a related question to this one. How would you set
up hadoop on eclipse if you dont want to download it from svn, rather you
just want to configure a stable release e.g 0.20.2 on eclipse. So, i want to
configure a stable release on eclipse and add/change the code i want and run
it through ant.

I've been able to build the code successfully in Eclipse by using the svn plugin and importing the code and using ant. I actually followed the wiki instructions and did an svn checkout inside Eclipse and was able to run all of the ant targets successfully.

Maybe the official way to build hadoop is using hudson, the developers just
using vim to make their work done, without IDE such as Eclipse.
In my opinion, hadoop did badly to cooperate with IDE.
