> Project: Hadoop Core
> Issue Type: Bug
> Components: ipc
> Affects Versions: 0.16.0
> Reporter: Hairong Kuang
> Assignee: Hairong Kuang
> Fix For: 0.17.0

> Attachments: closeConnection.patch, closeConnection1.patch,

>
> 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.
