[jira] [Updated] (HADOOP-12465) Incorrect javadoc in
WritableUtils.java
[ https://issues.apache.org/jira/browse/HADOOP-12465?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Junping Du updated HADOOP-12465:
--------------------------------
Fix Version/s: 2.8.0
> Incorrect javadoc in WritableUtils.java
> ---------------------------------------
>
> Key: HADOOP-12465
> URL: https://issues.apache.org/jira/browse/HADOOP-12465
> Project: Hadoop Common
> Issue Type: Bug
> Components: documentation
> Affects Versions: 2.7.1
> Reporter: Martin Petricek
> Assignee: Jagadesh Kiran N
> Priority: Minor
> Fix For: 2.8.0, 2.7.2, 3.0.0-alpha1
>
> Attachments: MAPREDUCE-6496-00.patch, MAPREDUCE-6496-01.patch
>
>
> 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.
