[jira] [Created] (MAPREDUCE-6496) Incorrect javadoc in WritableUtils.java

Martin Petricek created MAPREDUCE-6496:
------------------------------------------

             Summary: Incorrect javadoc in WritableUtils.java
                 Key: MAPREDUCE-6496
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6496
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 2.7.1
            Reporter: Martin Petricek
            Priority: Minor


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.
