Todd Lipcon reopened HADOOP-6724:
---------------------------------
Think we should commit this to branch-20 as well. It's pretty nasty and a
simple fix.

> If the socket factory throws an IOE inside setupIOStreams, then
> handleConnectionFailure will be called with socket still null, and thus
> generate an NPE on socket.close(). This ends up orphaning clients, etc.
