Zhijie Shen commented on YARN-2048:

Hi [~coderplay], what is the exact requirement? 2.4 has been already out, and 
YARN-1809 was not able to get in as we didn't have enough time test it 
thoroughly. Hence we target 2.5 for that jira, which should cover the scenario 

Usually we won't include major change in a maintain release, such as 2.4.1. 
However, if you think it is really urgent and required fix for 2.4.1, please 
feel free to reopen it, and set target version to 2.4.1. Thanks!

> Currently, Yarn haven't provide a way to list all of the containers of an 
> application from its web. This kind of information is needed by the 
> application user. They can conveniently know how many containers their 
> applications already acquired as well as which nodes those containers were 
> launched on.  They also want to view the logs of each container of an 
> application.
> One approach is maintain a container list in RMAppImpl and expose this info 
> to Application page. I will submit a patch soon
