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:
Compiling 5 source files to /usr/local/hadoop/build/classes
[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:
