             Summary: Merging the ApplicationClientProtocol and 
ApplicationHistoryProtocol
                 Key: YARN-1389
                 URL: https://issues.apache.org/jira/browse/YARN-1389
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Mayank Bansal
            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.
