Subject [jira] [Created] (HADOOP-8071) Avoid an extra packet in client code when nagling is disabled
Date Tue, 14 Feb 2012 05:36:59 GMT
Avoid an extra packet in client code when nagling is disabled
-------------------------------------------------------------

                 Key: HADOOP-8071
                 URL: https://issues.apache.org/jira/browse/HADOOP-8071
             Project: Hadoop Common
          Issue Type: Improvement
          Components: ipc
    Affects Versions: 0.23.1
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
            Priority: Minor


Currently, if you disable TCP_NODELAY in the IPC client, you get an extra packet for each
call which contains the call's length. This is unnecessary. Instead, we can just reserve the
4 bytes in the buffer up front, then go back to fill it in before pushing the call to the
wire.
