Karthik Kambatla commented on YARN-2175:
----------------------------------------

In our testing, we see this issue with the AM container itself potentially taking longer than 10 mins to localize and the RM kills this attempt since it hasn't heard from it.

> There are no timeouts that can be used to limit the time taken by various container startup operations. Localization for example could take a long time and there is no automated way to kill an task if its stuck in these states. These may have nothing to do with the task itself and could be an issue within the platform.
> Ideally there should be configurable limits for various states within the NodeManager to limit various states. The RM does not care about most of these and its only between AM and the NM. We can start by making these global configurable defaults and in future we can make it fancier by letting AM override them in the start container request. 
> This jira will be used to limit localization time and we can open others if we feel we need to limit other operations.
