java.lang.IllegalAccessError occur at run time when set default "bsp.user.name".

Error message is as below.
{code}
Exception in thread "main" java.lang.IllegalAccessError: tried to access method org.apache.hama.bsp.BSPJobClient.getUnixUserName()Ljava/lang/String;

I think the reason why this error was occurred is I accessed directly parent class method
"getUnixUserName()" which is not protected or public.
So I'll fix this issue soon.
