    Description

      Currently this two cleanup methods do not close all existing rpc connections. If a mini dfs cluster gets shutdown and then restarted as we do in TestFileCreation, RPCs in second mini cluster reuse the unclosed connections opened in the first run but there is no server running to serve the request. So the client get stuck waiting for the response forever if client side timeout gets removed as suggested by hadoop-2811.
