Kuhu Shukla commented on YARN-6315:
-----------------------------------
Thank you [~jlowe] for the reviews and help find out the bug with this
approach. I will update my patch shortly. Initial idea which seems to work when
I tested it was add "actualSize" to LocalizedResource and use that instead of
the request's size. Will update shortly,
> Improve LocalResourcesTrackerImpl#isResourcePresent to return false for
> corrupted files

> We currently check if a resource is present by making sure that the file
> exists locally. There can be a case where the LocalizationTracker thinks that
> it has the resource if the file exists but with size 0 or less than the
> "expected" size of the LocalResource. This JIRA tracks the change to harden
> the isResourcePresent call to address that case.
