pointers to Hadoop eclipse

Hi,
Can someone please point to any good reference that tells clearly how to
checkout Hadoop code base in eclipse, make any changes and re-compile.
Actually, I wanted to change some part in Hadoop, so wants to see the above
effect, preferrably in eclipse.

Thanks,
Bikash

I resolved these errors. I was missing tools.jar which I added as external
.jar file.

P.S.
On building the project in eclipse, I also get the following two errors:

Description Resource Path Location Type
The project was not built since its build path is incomplete. Cannot find
the class file for com.sun.javadoc.RootDoc. Fix the build path then try
building this project Hadoop Unknown Java Problem
The type com.sun.javadoc.RootDoc cannot be resolved. It is indirectly
referenced from required .class files

Re: pointers to Hadoop eclipse

Hi,
I followed the pointers to checkout Hadoop in eclipse and then compiled the
source.
The ant build for build.xml is showing successful, however under the
'Problem' tab in eclipse, I am getting the following error:

"AbstractDelegationTokenIdentifier cannot be resolved to a type"

Can anyone please help.

Thanks,
Bikash

Re: pointers to Hadoop eclipse

1) install svn plugin inside eclipse
2) specify the appropriate repository location for hadoop
3) check out code using the plugin inside eclipse
4) make code changes, compile using ant targets, also run tests

Hope that helps, let me know if you need more details.
