             Summary: YARN GPG mistakenly deleted applicationid
                 Key: YARN-11387
                 URL: https://issues.apache.org/jira/browse/YARN-11387
             Project: Hadoop YARN
          Issue Type: Bug
          Components: federation
    Affects Versions: 3.2.1
            Reporter: zhangjunj
         Attachments: yarn-gpg-mistakenly-deleted-applicationid.png

In [YARN-7599|https://issues.apache.org/jira/browse/YARN-7599], the Federation 
can delete expired applicationid, but  YARN GPG uses getRouter() method to 
obtain application information for multiple clusters. If there are too many 
applicationids that more than 200,000 , it will not be possible to pull all the 
applicationid information at one time, resulting in the possibility of 
accidental deletion. The following error is reported for spark component.
