TransportClient timeout / webserver configuration - JAVA Api

Hello,

I'm developing a tomcat webserver application that uses ElasticSearch 1.0
(Java API). There is a client facing desktop application that communicates
with the server so all the code for ElasticSearch is on that one instance
and it is used by all our clients. With that being said I am running into
this issue: After initializing a new TransportClient object and performing
some operation on it, there is a chance that i could sit idle for a very
long time. When does sit idle for a long time it gets this error:

Mar 08, 2014 1:15:37 AM org.elasticsearch.client.transport

INFO: [Elven] failed to get node info for
[#transport#-1][WIN7-113-00726][inet[/159.140.213.87:9300]],

Is there any way to prevent this from happening? I know the ideal situation
would be that after every request the transport client is closed. But since
it lives on a webserver with lots of search requests coming in, we would
ideally like it to stay open because it takes 3-4 seconds for a transport
client to initialize and we are going for speed here.

Also since we are having one central server to handle all search and index
requests, can the TransportClient handle multiple simultaneous requests from
different users at the same time? We just want to make sure that we are
doing this correctly.

Hey,

can you create a github issue about this? An NPE should not happen. Please
provide as much information as possible about your setup (see
Elasticsearch Platform — Find real-time answers at scale | Elastic) like es version, operating system, your
elasticsearch setup etc...
Thanks a lot!
