Hello,
I will test/evaluate ElasticSearch with a hadoop gateway. I think
something is wrong in my configuration. I hope anybody can help me.
My configuration
...

Which version of hadoop are you working with? The hadoop plugin comes with
0.20.2, but you can replace the jars if you want (have a look at the plugins
dir).
