28 * A KeepAlive connection is not physically closed immediately after the close,

31 * This interface is used by a dynamic proxy. It allows to have a #close
32 * function in a master client.

34 * This class is intended to be used internally by HBase classes that need to
35 * speak the MasterMonitorProtocol; but not by final user code. Hence it's
