Subject hadoop ANT build ERROR HELP!!!!
Date Tue, 03 Aug 2010 11:27:01 GMT
Hi All,
          Can anyone guide me regarding this error, i get this error when i
compile the hadoop with ant. one more thing, i just un tar the hadoop
folder, so, i have changed nothing no code in hadoop directory.

When 'ant' it says:

    [javac] Annotation processing got disabled, since it requires a 1.6
compliant JVM

gives me a long list of warning and a few errors like:
