You may want to do this for security though, no? Since ES does not have
authentication, SSL, etc. it may make sense to have a front end that is a no
data node, and keep ES data nodes behind a firewall, only accessible via the
front end.

In general, its a good practice to have all your nodes data nodes. If you
have a machine that is just hosting an HTTP ES proxy node (non data), then
its probably wasteful, and its better to have it as a data node to shared
the load.

Thanks for your input.
Actually, what I am really wondering is the benefit of doing the
indexing on a non-data node. The documentation
http://www.elasticsearch.com/docs/elasticsearch/modules/node/data_node/
explains well the benefit of running queries on a non-data node but
for indexing, is there a significant gain to run indexing requests on
a non-data node?
Thanks,
Colin

The best way to answer this is to run some load tests using your
incoming documents and your typical index queries.
We run four nodes all in a data configuration. We use the Java API for
indexing and searching. Our typical index load is 5-35 index requests
per second, this provides nearly no load. Our searches span multiple
indexes and have 10-25 criteria. Our search load is 100-150 queries/
sec against 31M docs, which we handle in the 34-40ms range.
