When an admin does a {{-transitionToActive}} during this transfer, part of that is interrupting an ongoing checkpoint so we can transition immediately. > However, the {{thread.interrupt()}} in {{StandbyCheckpointer#stop}} gets swallowed by {{connection.getResponseCode()}} in {{TransferFsImage#doGetUrl}}. None of the methods in HttpURLConnection throw InterruptedException, so we need to do something else (perhaps HttpClient [1]): > [1]: http://hc.apache.org/httpclient-3.x/ -- This message is automatically generated by JIRA.
