Subject [jira] [Created] (YARN-1364) Limit the number of outstanding tfile writers in FileSystemApplicationHistoryStore
Date Wed, 30 Oct 2013 00:51:25 GMT
Zhijie Shen created YARN-1364:
---------------------------------

             Summary: Limit the number of outstanding tfile writers in FileSystemApplicationHistoryStore
                 Key: YARN-1364
                 URL: https://issues.apache.org/jira/browse/YARN-1364
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Zhijie Shen
            Assignee: Zhijie Shen


It seems to be expensive to maintain a big number of outstanding t-file writers. RM is likely
to run out of the I/O resources. Probably we'd like to limit the number of concurrent outstanding
t-file writers, and queue the writing requests.
