             Summary: Container localization has no timeouts and tasks can be 
stuck there for a long time
                 Key: YARN-2175
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
            Reporter: Anubhav Dhoot

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 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 

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 open others if we feel 
we need to limit other operations.
