-----------------------------------
Summary: Need a state for Localized resources that indicates if
the localization is in progress
Key: YARN-8966
URL: https://issues.apache.org/jira/browse/YARN-8966
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Chandni Singh
Assignee: Chandni Singh
Refer YARN-8867.
Following are some existing limitations in the code of
ResourceLocalizationService and LocalizedResource that makes it difficult to
differentiate the resources which are queued from the ones for which
localization is in progress:
# LocalizedResource state does not differentiate between resources that are
queued and the ones which are actually in-progress. For both of them, the state
is DOWNLOADING
# In ResourceLocalizationService.LocalizerRunner, the pending collection holds
the resources that are queued as well as submitted. Items from this list is not
removed even when they are submitted. They are removed only when the state
changes from DOWNLOADING to localized or localization failed.
