>          Components: documentation
>    Affects Versions: 2.7.1
>            Reporter: Martin Petricek
>            Assignee: Jagadesh Kiran N
>            Priority: Minor
>             Fix For: 2.7.2

> Documentation for writeVLong in WritableUtils states that "For
>  -112 <= i <= 127, only one byte is used"
> Documentation for writeVInt states that "For -120 <= i <= 127, only one byte is used"
> writeVInt calls internally writeVLong, so the ranges are the same for both functions. 
> After examining the code, I see that the documentation that is at writeVLong is correct.
> Documentation for writeVInt is therefore incorrect and should be fixed.
