      Description

      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)

      Which means almost every randomly generated block ID exceeds MAX_SAFE_INTEGER.

      A integer which exceeds MAX_SAFE_INTEGER cannot be represented in Javascript.
