Subject Re: Hadoop error
Date Tue, 15 Jun 2010 14:07:26 GMT
Hi,

I am trying to set up a development cluster for hadoop 0.20.1 in eclipse.
I used this url
http://svn.apache.org/repos/asf/hadoop/common/tags/release-0.20.2/ to
check out the build. I compiled "compile , compile-core-test , and
eclipse-files" using ant. Then when I build the project , I am getting
errors in bin/benchmarks directory. I have followed the screencast from
cloudera
http://www.cloudera.com/blog/2009/04/configuring-eclipse-for-hadoop-development-a-screencast/.
