> Old release use randomly generated block ID(HDFS-4645).
> max value of Long in Java is 2^63-1
> max value of -number-(*integer*) in Javascript is 2^53-1. ( See
> [Link|https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Number/MAX_SAFE_INTEGER])
> Which means almost every randomly generated block ID exceeds MAX_SAFE_INTEGER.
> A integer which exceeds MAX_SAFE_INTEGER cannot be represented in Javascript.
