I am still not able to compile scheduler code in Hadoop-0.21
I tried to use eclipse and svn checkout.
I have the trunk, right click on the fairshare build.xml file and run.
However, I got a bunch of errors like:
[ivy:cachepath] :: loading settings :: file =
/home/rgrandl/School/Project/hadoop_compile/hadoop_trunk1/trunk/ivy/ivysettings.xml

as it seems I don't have package org.apache.hadoop.mapreduce.
Could somebody point me out how to compile the code ?
I am not such an expert on using eclipse but also don't know how to try
other solution.
Thank you very much for any help,
Robert

Thanks for your reply.
However, I don't know what is Maven repository.
Could you be more detailed on what exactly I should put where ?
I would like an easy way to recompile schedulers source code.
Many thanks,
Robert

0.21.0 jars aren't in Maven yet. I think they'll be in after 0.21.1.
For now, add those jars to your local maven repository manually to get
the build working.
Or you could use trunk, if it is purely for development purposes.
