> Sometimes when primary crashes during image transfer secondary namenode would
> hang trying to read the image from HTTP connection forever.
> It would be great to set timeouts on the connection so if something like that
> happens there is no need to restart the secondary itself.
> In our case restarting components is handled by the set of scripts and since
> the Secondary as the process is running it would just stay hung until we get
> an alarm saying the checkpointing doesn't happen.
