---------------------------------
Summary: better Logging in DNS.java
Key: HADOOP-11072
URL: https://issues.apache.org/jira/browse/HADOOP-11072
Project: Hadoop Common
Issue Type: Improvement
Affects Versions: 2.4.0, 2.3.0
Reporter: jay vyas
Priority: Minor
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.
