> In createSocketForPipeline(), connect() is called with a timeout set to (socket_timeout
+ read_extension * num_datanodes). Since it is simply connecting to a single node, it does
not make sense to increase connection timeout based on the number of datanodes.
> DFSInputStream is doing it correctly both in trunk and branch-2.
