Hi all,
I encountered a strange problem while I am trying to build the hadoop source 
code. I used the command line "ant -file build.xml" to build the source code 
and all the three parts can be built successfully. Then I tried another way 
using subversion in eclipse. I first checked out the code using subclipse and 
then set the ant builder. Before, all the three parts can be built successfully 
using this method. But today, mapreduce part failed the build with the 
following information: (I just re-prepared the build environment and this issue 
appeared)
