--------------------------------------

             Summary: Specify per user quota for private/application cache and 
user log files
                 Key: YARN-882
                 URL: https://issues.apache.org/jira/browse/YARN-882
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Omkar Vinit Joshi
            Assignee: Omkar Vinit Joshi


At present there is no limit on the number of files / size of the files 
localized by single user. Similarly there is no limit on the size of the log 
files created by user via running containers.
We need to restrict the user for this. For LocalizedResources; this has serious 
concerns in case of secured environment where malicious user can start one 
container and localize resources whose total size >= 
DEFAULT_NM_LOCALIZER_CACHE_TARGET_SIZE_MB. Thereafter it will either fail (if 
no extra space is present on disk) or deletion service will keep removing 
localized files for other containers/applications. 
The limit for logs/localized resource should be decided by RM and sent to NM 
via secured containerToken. All these configurations should per container 
instead of per user or per nm.
