---------------------------------------------
> That's a change from what you stated in action_12550831.
I don't see any contradiction. Besides I already said that many times after
that, if you read a little bit further down
[#action_12551673] and [#action_12553565].
Providing partial conversion is a compromise, which I am willing to accept.
This is temporary for one release, that is why all related code is deprecated
in my patch.

"some processing" of exactly these parameters was introduced in HADOOP-1085. [I
opposed it
then.|https://issues.apache.org/jira/browse/HADOOP-1085?focusedCommentId=12483800#action_12483800]
You just committed it.
If dozens of files is not widespread then what is.
The only thing I agree with you upon is that configuration needs accessors.
But I do not agree that they should be introdueced in this patch, which will
lead to massive changes,
and I do not support *static* accessors, and I do not see any of these is
supported by anybody else.
This argument is going on for almost a month now. I do not find it productive.
Unless the compromise proposed by Dhruba is acceptable for you,
I am planning to submit the bug fix mentioned by Devaraj in a separate issue,
and let somebody else deal with this one.
I mean, people can have different opinions, what do you do with that.

> 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}
