Hi Jörg, I have run the code successfully after I deleted the old ES version in another machine. What's the reason to this error even the ES in another machine is not initialized? Thanks for your time so much!!!

I think there was another node up and running. You can check this by looking at the hosts on the network. At ports 9300..9400, if ports are open for listening, you can be sure there is an ES node active. The EOFException is somehow unexpected when versions are mixed. But, since the internal ES data structures change in a new version, they grow in length. So if an old ES version responds with a short answer, the new ES node waits for a longer version. But on the network layer, the connection closes, and the new ES node gets notified with an EOFException. For the future, Elasticsearch send magical version headers in all the data transports which allow to detect the version of ES nodes which is currently being talked to. So, new ES versions can deny data transport more gracefully with a nice hint, and no more low level network expections will happen.

Thanks for your explanation. Your demo code shows how to create index and query meanwhile after refresh. What should I do if I want I create an Index with it active, and query it when I need, because I need to add some documents into the index ceaselessly. Besides, I still do not find the error in my early code. ☹ On Tue, Mar 5, 2013 at 7:25 PM, Jörg Prante [joergprante@gmail.com](mailto:joergprante@gmail.com) wrote: > I think there was another node up and running.

Just put the query part elsewhere. You can consider using a river for your indexing routine. A river is nothing but a plugin with a client that fetches data from a source, and enters a loop for indexing data contineously, e.g. from a file, a database, or a stream data source.

Hi Jörg and David, I have resolved this problem, it was caused by different versions. Because I ever used ES 0.20 before, so I referenced the jars in ES 0.20 in my project. However, I forgot to re-reference these jars in my project after I changed ES from 0.20 to 0.90. The program could work after I resolved it. I would express my sincerest thanks to both of your for your times and great help.
