Konstantin Shvachko commented on HADOOP-2404:
---------------------------------------------
I agree with Hemanth. Why changing names again.
- Everybody has already adapted to the previous ones.
- The patch does not address issues brought up by Doug.
- There are 3 solutions that don't change names.
- And I seriously don't understand why you removed default values in getters.
Just let this issue rest in peace.

> {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
