--------------------------------------------
Summary: Support asynchronous RPC calls
Key: HADOOP-12909
URL: https://issues.apache.org/jira/browse/HADOOP-12909
Project: Hadoop Common
Issue Type: New Feature
Components: ipc
Reporter: Tsz Wo Nicholas Sze
Assignee: Xiaobing Zhou
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, synchronized 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.
