Hi all !

 I have downloaded hadoop-0.21.I am behind my college proxy.
 I get the following error while building mumak :

$cd /home/arun/Documents/hadoop-0.21.0/mapred
$ant package
Buildfile: build.xml

clover.setup:

clover.info:
     [echo] 
     [echo]      Clover not found. Code coverage reports disabled.
     [echo]   

clover:

ivy-download:
