Colin Patrick McCabe updated HADOOP-11072:
------------------------------------------
Issue Type: Bug (was: Sub-task)
Parent: (was: HADOOP-3619)
> better Logging in DNS.java
> ---------------------------
>
> Key: HADOOP-11072
> URL: https://issues.apache.org/jira/browse/HADOOP-11072
> Project: Hadoop Common
> Issue Type: Bug
> Components: net
> Affects Versions: 2.3.0, 2.4.0
> Reporter: jay vyas
> Priority: Minor
> Labels: logging
>
> The DNS.java class should be more informative, and possibly fail early when
> reverse DNS is broken. Right now it is vulnerable to a cryptic ArrayIndex
> exception.
> {noformat}
> parts = hostIp.getHostAddress(....)
> String reverseIp = parts[3] + parts[2] ...
> {noformat}
> During this patch I think we can also improve a couple other minor logging
> statements in the net package.
