Subject [jira] [Updated] (YARN-2175) Container localization has no timeouts and tasks can be stuck there for a long time
Date Tue, 01 Jul 2014 19:22:25 GMT

     [ https://issues.apache.org/jira/browse/YARN-2175?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Anubhav Dhoot updated YARN-2175:
--------------------------------

    Description: 
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.
