Hey guys, I have 3 nodes, one of which I just added recently, ever since I keep seeing this error "Failed to deserialize exception response from stream". The only thing I see different in the new node is the java version which is newer in the new node. I wanted to upgrade the version on the old nodes but was wondering if any of you has done this before or if there is any problems that could arise Thanks for the help -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Shut down a node, install new Java, start the node, then move to the next node. But consider there may be a downtime while nodes are recovering after start. In my case 15-20 minutes. If you let recover each node before moving on to the next node, there is no interruption of service. Or just stop all nodes, update java, and restart nodes again. It's easy and the fastest method I know but service is interrupted.

Thanks Jörg. I thought about doing this. I just didn't know if my nodes would recover from it. I'll give this a try and report back On Wed, Mar 6, 2013 at 3:03 PM, Jörg Prante [joergprante@gmail.com](mailto:joergprante@gmail.com) wrote: > Shut down a node, install new Java, start the node, then move to the next > node.

Yes. As Jörg said, it's sometimes better to have one minute of full interruption than one hour of doing some recovery process without _real_ interruption. Also be aware that you need enough disk space to have replicas copied to the remaining nodes. ## My 2 cents David Pilato | Technical Advocate | [Elasticsearch.com](http://Elasticsearch.com) @dadoonet | @elasticsearchfr | @scrutmydocs Le 6 mars 2013 à 19:03, Jörg Prante [joergprante@gmail.com](mailto:joergprante@gmail.com) a écrit : > Shut down a node, install new Java, start the node, then move to the next node.
