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

             Summary: Refactoring the code which computes the user file cache and user application file cache paths
                 Key: YARN-601
                 URL: https://issues.apache.org/jira/browse/YARN-601
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Omkar Vinit Joshi
            Priority: Minor


At present at multiple places user local cache file path and user application file path are getting calculated.
It is better to expose them as a single static utility method and reuse them everywhere else.
Locations :
* ContainerLaunch
* DefaultContainerExecutor: this already has some methods like this
* ResourceLocalizationService: getUserCacheFilePath getAppFileCachePath
* ContainerLocalizer
* ShuffleHandler.Shuffle
* TestContainerLocalizer, TestContainerManager, TestDefaultContainerExecutor and TestResourceLocalizationService.
