> HADOOP_CLASSPATH tends to be used to add to bin/hadoop's classpath.  Because of the way the comment is written, administrator's who customize hadoop-env.sh often inadvertently disable user's abilities to use it, by not including the present value of the variable.
> I propose we change the commented out suggestion code to include the present value.
> {noformat}
>  # Extra Java CLASSPATH elements.  Optional.
> -# export HADOOP_CLASSPATH=
> +# export HADOOP_CLASSPATH="<extra_entries>:$HADOOP_CLASSPATH"
> {noformat}
