Version 5.6 will fully support Hive 2 - I am using Cloudera Impala for some demo work and getting very impressive performance results with it. I beleive that the Community Edition will also support connectivity to Hive2 as well. As for the release date, I can not comment on that, but we are getting close at this point.
Yes - you can use the WAR file distribution on server 1 - 3 in order to skip the postgres install and point them to the repo DB on server 4. This will require you to do the following: Manually install Postgres on server 4. Manually create the repostiory on your Postgres instance (see chapter 6 of the JasperReports-Server-Install-Guide) Manually install Tomcat on servers 1 - 3 Use the WAR file distribution to install JRS (see chapter 5 of the JasperReports-Server-Install-Guide) A word of caution- if you are using a load balancer in front of servers 1 - 3, you have to configure it for 'sticky session'. Once a session is established, it needs to reamin on the server it started on.
