Xiaobing Zhou commented on HADOOP-12909:
----------------------------------------
Patch v008 addressed all your latest comments except adding new tests. I will
add them in next patch. The benefit of TestAsyncIPC extending TestIPC is to
reuse most of IPC test logic and make them working correctly for both cases of
sync and async. Those that can't be reused go to TestAsyncIPC, e.g.
SerialCaller. TestIPC keeps stable as is. Thanks [~szetszwo] for review.

> In ipc.Client, the underlying mechanism is already supporting asynchronous
> calls -- the calls shares a connection, the call requests are sent using a
> thread pool and the responses can be out of order. Indeed, synchronous call
> is implemented by invoking wait() in the caller thread in order to wait for
> the server response.
> In this JIRA, we change ipc.Client to support asynchronous mode. In
> asynchronous mode, it return once the request has been sent out but not wait
> for the response from the server.
