Eric Yang created AMBARI-20289: ---------------------------------- Summary: Optional host_group can interfere with actual deployment Key: AMBARI-20289 URL: https://issues.apache.org/jira/browse/AMBARI-20289 Project: Ambari Issue Type: Improvement Affects Versions: 2.4.2 Reporter: Eric Yang
User defines a blueprint that contains 4 host groups. Edge group, management group 1 and 2, and worker group. For management group 1, include a single knox server. In edge group, also define Knox server. When edge group includes one or more hosts, they will be used for Knox Server HA. Without edge group, management group 1 will be used as a single Knox server. When edge group does not contain any host, Ambari throws a weird exception: {code} 26 Feb 2017 19:14:55,108 WARN [pool-16-thread-1] BlueprintConfigurationProcessor:1403 - The property 'dfs.namenode.secondary.http-address' is associated with the component 'SECONDARY_NAMENODE' which isn't mapped to any host group.
