> Now It's not directly to understand the output result of the {{FileDistribution}} processor
that in hdfs oiv command for users. For example, this is a original output:
> {code}
> Size    NumFiles
> 0       22556
> 1048576 404971
> 2097152 29259
> 3145728 16937
> 4194304 9197
> 5242880 6889
> 6291456 4930
> 7340032 4070
> 8388608 299384
> 9437184 274623
> {code}
> Two aspects make that  hard to understand for users.
> First, the size column just showed as the number in byte, it's not readable here. The
better way is showed with a binary prefix.
> Second, the size column would be better to showed as a size range. It will let users
know the value in {{NumFiles}} column was counted from A size to B size.
> The expected output result should be this:
> {code}
> Size Range   NumFiles
> (0 B, 0 B]  1666332
> (0 B, 1 M]        778473
> (1 M, 2 M]      35125
> (2 M, 3 M]      13978
> (3 M, 4 M]      10158
> (4 M, 5 M]      6970
> {code}
