Subject Re: building mapreduce project on eclipse
Date Fri, 15 Oct 2010 20:52:08 GMT
Hey Goutham,

Add separate common, hdfs and mr projects to your workspace. Then for
the hdfs and mapreduce projects, select Build Path -> Configure Build
Path, in the Projects tab of the Java Build Path add dependencies on
the other projects. hdfs should depend on common, and mapreduce should
depend on hdfs and common.
