Hi all. I'm developing my own stack for Ambari and I often need to change master/slave component code in Python. And I have 2 questions regarding this:
1. What is the fastest way to make Ambari understand that stack has changed and to use updated code ? The only way it works for me now is to restart server (service ambari-server restart) Is it possible to do it any other way without restarting the server ? 2. Ambari server start procedure really takes too long. I'm using Centos 7 and after starting the service it takes at about 4-8 minutes for it to actually bind to port 8080 so that web ui becomes available. Tailing -f ambari-server.log I've notices that the biggest delay during start is on this step: 16 Nov 2015 08:47:13,392 INFO [main] ControllerModule:560 - Binding and registering notification dispatcher class org.apache.ambari.server.notifications.dispatchers.AlertScriptDispatcher Maybe someone experienced the same behavior and there is a way to speed up this step? Thanks in advance. -- Kostiantyn Yarovyi
