Review comment:
public static String humanReadableBytes(long bytes) {
int unit = 1024;
if (bytes < unit) {
return bytes + " B";
}
int exp = (int) (Math.log(bytes) / Math.log(unit));
char pre = "KMGTPE".charAt(exp - 1);
return String.format("%.3f %cB", bytes / Math.pow(unit, exp), pre);
}
put it to org.apache.servicecomb.foundation.common.net.NetUtils
