You could always write code that executes a scan/scroll query from one
cluster and bulk loads them into the other. Perhaps one of the existing
reindex plugins can help:

You can do this with the export/import functions of my knapsack plugin

there are rivers for mysql,mongodb, so is there a river for elasticsearch
it self?

No. IIRC relative issue has been closed in github.

You can start up remote nodes and connect them (directly or via IP
tunnels) to form a cluster so the nodes span data centers. With
awareness, you can configure ES to take the node distribution into
account, for shard allocation.

But heck no, there is no elasticsearch river. A river is primarily meant
being a one-way mechanism to fetch data from foreign sources. I think I
can plug code from my JDBC river and knapsack plugin together to achieve
this in a very naive style.

For ES 1.0, there were some feature announcements. One is the full
fledged backup/restore feature (maybe even on hot clusters) from which I
hope this feature can span clusters/data centers. No details yet, but
I'm excited. Maybe also with the feature of keeping two ES clusters in
sync on a slow connection.
