Coordinating NodesΒΆ


Figure 1. Typical setup of Coordinating Nodes in an environment. The primary CN is the CN with the environment DNS entry pointing to it. The primary CN must have d1-processing running on it. The indexing CN is the CN that has both d1-index-task-generator and d1-index-task-processor running on it. The indexing CN may also be the primary CN. All CNs in an environment have ldap, postgres, apache, zookeeper, solr, and tomcat7 running on them.
