Examples of org.apache.hadoop.ipc.Client.call()

org.apache.hadoop.ipc.Client.call()
Make a call, passing param, to the IPC server running at address, returning the value. Throws exceptions if there are network problems or if the remote code threw an exception. @deprecated Use {@link #call(Writable,ConnectionId)} instead
