[jira] [Commented] (YARN-467) Jobs fail during resource
localization when public distributed-cache hits unix directory limits
[ https://issues.apache.org/jira/browse/YARN-467?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13618997#comment-13618997 ]
Siddharth Seth commented on YARN-467:
-------------------------------------
bq. Another thing I've been looking hard is to see if LocalResourceTracker.localizationCompleted() can be done away with completely in favour of the handle() method. But to do that we need to handle both successful and failing localizations via handle(). I can already see a couple of bugs related to localization failures, so let's do this separately.
That could be the route to reach the LocalizedResources, instaed of sending events to them directly. IAC, can be figured out in the follow-up jiras.
Had looked at this patch earlier as well; mostly looks good in terms of functionality. It was a little tough to read, hopefully some of the changes suggested by Vinod will make that easier.
