-----------------------------------
+ jthr = newException(env, "java/net/BindException",

I think you reversed the order of your %s parameters here. Otherwise +1

> In cluster-testing HDFS-347, we found that in clusters where the MR job
> doesn't run as the same user as HDFS, clients wouldn't use short circuit read
> because of a 'permission denied' error connecting to the socket. It turns out
> that, in order to connect to a socket, clients need write permissions on the
> socket file.
> The DN should set these permissions automatically after it creates the socket.
