I don't think there are any known deployments of Hadoop over WAN. There
aren't any WAN specific tweaks or configuration settings present that I
know of.
Hadoop apps tend to be data intensive. Any more details what the
configuration likely to be? Will HDFS itself be across WAN?
Some exmpale tweaks could be, if you have a high latency and high
bandwidth across WAN, each socket connection might need use large
recv/send buffers for TCP sockets to mask latency.

How well does HDFS perform over WAN links? Any best practices to take

Thanks!
