Hi All, We are currently developing Custom Stack based on Ambari 2.2.0. We are in the mist of planning for upgrade version of the Custom Stack.
The closest documentation I could find is at https://cwiki.apache.org/confluence/display/AMBARI/How-To+Define+Stacks+and+Services#How-ToDefineStacksandServices-StackAdvisor Under the heading *Stack Upgrades*. There consist examples of Upgrade Packs XML. However there are a few items which I am still unclear as below, 1. From the contents of https://github.com/apache/ambari/blob/branch-2.2.1/ambari-server/src/main/resources/ *stacks/HDP/2.3/upgrades/upgrade-2.4.xml*. Does it mean that when we rolled out Customer Stack 1.0, we need to include the upgrade pack xml along with it already, say for 1.1? Meaning in the Stack directory, we would expect /var/lib/ambari-server/resources/ *stacks/CustomStack/1.0/upgrades/upgrade-1.1.xml*? 2. Is there a documentation that explains how to use the Upgrade Pack XML? For example the tag usage? Thanks in advance!
