Todd Lipcon commented on HDFS-3330:
-----------------------------------
This does appear to affect branch-1. Does anyone mind if I just commit the fix
(change the catch clause to catch all Throwable) without the tests in branch-1?
TestCheckpoint is substantially different.

> Currently in GetImageServlet, we catch Exception but not other Errors or
> RTEs. So, if the code ends up throwing one of these exceptions, the
> "response.sendError()" code doesn't run, but the finally clause does run.
> This results in the servlet returning HTTP 200 OK and an empty response,
> which causes the client to think it got a successful image transfer.
