[jira] [Updated] (HADOOP-12909) Support asynchronous RPC calls

     [ https://issues.apache.org/jira/browse/HADOOP-12909?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.
