Adjusting the Jetty configuration to avoid deadlocks

Adjusting Jetty to properly handle all the requests sent to Solr and SolrCloud is very important. The request that the application sends to Solr is one, but it is also important to allow Solr to process the internal requests sent between nodes and shards. Because of this we need to prepare our container to handle a higher number of requests than usual. This recipe will show and discuss how to properly set up Jetty to handle traffic to and between Solr nodes.

Getting ready

If you are not familiar with how to set up Jetty, please refer to Running Solr on a standalone Jetty recipe in Chapter 1, Apache Solr Configuration, before proceeding. I also assume that we are using Jetty 8.1.10 and Solr 4.x, which was distributed as a WAR file.

How to do it...

I assume that each of the Solr instances will run on its own Jetty container. Each of the Jetty servers has the jetty.xml file that we will need to alter (this file should be present in the $JETTY_HOME...
