Doug Cutting commented on HADOOP-2404:
--------------------------------------
There are six parameters involved. So that's six methods at most, and they're
pretty trivial methods, no more complex than the back-compatibility patch
already submitted.
public static InetSocketAddress
SecondaryNamenode#getInfoBindAddress(Configuration conf);
public static InetSocketAddress DataNode#getInfoBindAddress(Configuration conf)
{}
...
That doesn't seem like it should take too much design effort. This issue,
unlike HADOOP-2385, isn't about improved error checking, its about
back-compatibility. So HADOOP-2385 might improve the error checking of these
methods, but this issue can add such methods where required for
back-compatibility, and change places that currently directly access the
configuration to instead call these methods.

> Key: HADOOP-2404
> URL: https://issues.apache.org/jira/browse/HADOOP-2404
> Project: Hadoop
> Issue Type: Bug
> Components: conf
> Affects Versions: 0.16.0
> Reporter: Arun C Murthy
> Assignee: Konstantin Shvachko
> Priority: Blocker
> Fix For: 0.16.0
>
> Attachments: ConfigurationConverter.patch

>
> HADOOP-2185 removed the following configuration parameters:
> {noformat}
> dfs.secondary.info.port
> dfs.datanode.port
> dfs.info.port
> mapred.job.tracker.info.port
> tasktracker.http.port
> {noformat}
> and changed the following configuration parameters:
> {noformat}
> dfs.secondary.info.bindAddress
> dfs.datanode.bindAddress
> dfs.info.bindAddress
> mapred.job.tracker.info.bindAddress
> mapred.task.tracker.report.bindAddress
> tasktracker.http.bindAddress
> {noformat}
> without a backward-compatibility story.
> Lots are applications/cluster-configurations are prone to fail hence, we need
> a way to keep things working as-is for 0.16.0 and remove them for 0.17.0.
