Spark cluster spanning multiple data centers

[Ray Qiu]

Hi,

Is it feasible to deploy a Spark cluster spanning multiple data centers if
there is fast connections with not too high latency (30ms) between them?  I
don't know whether there is any presumptions in the software expecting all
cluster nodes to be local (super low latency, for instance).  Has anyone
tried this?

Thanks,
Ray
