Tsz Wo Nicholas Sze updated HADOOP-12909:
-----------------------------------------
Description:
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.
