hadoop pipes problem

[stchu <st...@gmail.com>]

Hi,

I tried to use Hadoop Pipes for C++. The program was copied from the Hadoop
Wiki: http://wiki.apache.org/hadoop/C++WordCount.
But I am confused about the file name and the path. Should the program be
named as "examples"? And where should I put this code
for compiling by ant? I used the name:"examples" and put it to
{$HADOOP_HOME}/src/examples/pipes/. When I typed the instruction:
ant -Dcompile.c++=yes examples, I got the message as followed:

The Hadoop version is 0.18.1, and the jdk path has been set. Can anyone give
me some suggestions or guides?
Thanks a lot.
